Image Standards

Image Standards · Revised July 2026

A working guide

Image standards — aesthetics, speed, and consistency.

The images you upload shape three things visitors judge the theatre by: how the site looks, how fast it loads, and how professional the brand feels. This guide covers the specs for every image context on the site, plus the prep steps that keep them tight.

01

Why standards matter

Three things move together when image discipline slips.

Aesthetics. The theatre’s site uses a consistent 16:9 landscape frame across sliders, event cards, and show landing pages. When someone uploads a portrait phone photo, it gets cropped or letterboxed and looks amateur next to the rest. Consistent aspect ratios are the single most important brand cue.

Speed. A raw iPhone photo is often 4032 × 3024 pixels and 4–6 MB. The site auto-scales it down for display, but the visitor still downloads the full file. On a phone with weak signal, that adds 3–8 seconds of load time per image. Multiply by 4 event cards on the homepage and mobile visitors bounce before they see anything.

SEO and search discovery. Google Search, Google Maps, Google’s “Things to Do” carousel, and social share previews all use whatever image you upload. If it’s blurry, wrong-aspect, or too heavy, your organic reach shrinks — regardless of how good the content is.

02

The golden rules

Follow these four rules and 95% of the work is done.

  1. Landscape 16:9 orientation for hero images, event posters, and slider slides. Portrait works only for playbill front covers.
  2. Under 500 KB per file, always. If you’re above, compress before uploading.
  3. JPG for photography, PNG for graphics with typography. WebP works too but isn’t universal — stick to JPG/PNG.
  4. Every image needs alt text. Describe what’s in the image, not “poster for X”.

Why “under 500 KB”?

Google’s mobile page-speed target is under 3 seconds on a 4G connection. Every 500 KB of images adds roughly 1 second on cellular. Four images at 500 KB each = 2 seconds of just images. Anything over that dilutes conversion measurably.

03

Where images appear on the site

Each context has a specific size and treatment. Pick the right one for what you’re uploading.

Homepage slider (Slider Revolution)
1920 × 1080 px, 16:9 landscape. The rotating hero at the top of the homepage. Keep critical text and faces in the center-left — the right third gets overlay text. Under 500 KB. See the Slider Revolution guide for full details.
Event featured image
1600 × 900 px minimum, 16:9 landscape. The poster on the event page, the card thumbnail on the homepage, the Google search preview, and the social share image. One well-prepared file covers all four. Under 500 KB.
Show Run hero (landing pages)
1920 × 1080 px, 16:9 landscape. The full-width hero at the top of a multi-night show’s landing page (like In the Heights). Bigger than an event poster because it spans the full page width.
Featured Show Hub card thumbnail
Uses the containing post’s featured image. Same 1600 × 900 spec as event posters — one image, all contexts. Set the featured image on the post; the hub card picks it up automatically.
Playbill front cover
850 × 1100 px (letter portrait) OR export first PDF page as PNG. This is the ONE case where portrait orientation is correct — playbill programs are read as books. Shows as the card on the /playbills/ archive.
Inline images in post content
1200 × 675 px (16:9) or narrower. Photos inside post bodies — cast headshots, backstage photos, sponsor logos. WordPress scales down for display but keeps quality on retina screens. Under 300 KB is ideal here since these usually appear alongside other images.
Google Business Profile posts (auto)
The GBP integration auto-uses the event’s featured image. No separate upload needed — GBP wants 1200 × 900 minimum, and our featured-image spec exceeds that.
Social sharing (Open Graph)
Facebook and X (Twitter) both use the post/page’s featured image as the share preview. Meeting the featured-image spec means every share automatically looks right — no separate “social image” needed.

04

Preparing images before upload

The three steps that separate a fast, sharp site from a slow, blurry one.

  1. Crop to 16:9. Use Preview (Mac), Windows Photos, or any editor. If starting from a portrait phone photo, crop tightly to keep faces intact.
  2. Resize to the target dimensions. Never rely on the browser to shrink a 4032 × 3024 image to display at 800 × 450 — that’s four times more data than needed. Set your export to exactly the recommended size for the context.
  3. Compress. Export at 80% JPG quality (or run through a compressor like TinyPNG / Squoosh). Check the file size before uploading — if it’s above 500 KB, compress more.

The biggest mistake — uploading from phone

Do not drag a photo straight from iPhone Photos into WordPress. A raw phone photo is 4–6 MB, wrong aspect ratio, and often the wrong orientation (portrait). Take 30 seconds to crop, resize, and compress. It’s the single change that speeds up the site more than anything else.

05

Format & compression

Different image types compress differently. Pick right and save 50-80% of file size.

JPG (or JPEG)
Photography — production shots, cast photos, venue interiors, sponsor banners. 80% quality on export is invisible to viewers but cuts file size by 60%.
PNG
Graphics with typography — show posters with the title rendered as art, logos, screenshots. Preserves crisp edges. Bigger files than JPG for photos, but essential when text is part of the image.
WebP
Newer format, 25-35% smaller than JPG for equivalent quality. WordPress supports it. Fine to use, but not required — JPG/PNG are the safe defaults.
SVG
Vector logos and icons only. Do not upload without confirming with the site administrator (SVGs can contain scripts and pose a security risk if uploaded from untrusted sources).
GIF / animated
Avoid. Modern replacements: an MP4 video embedded via YouTube, or a short WebP animation. Old animated GIFs bloat pages and rarely serve a real purpose.

06

Alt text & filenames

Two small text fields that matter more than most people realize.

Alt text

The Alternative Text field appears when you upload or edit an image. It’s used by:

  • Screen readers — visually impaired visitors hear this description read aloud. Accessibility requirement.
  • Google image search — Google uses alt text to understand what the image contains.
  • Broken-image fallback — if the image fails to load, the alt text shows instead.

Good alt text describes the image contents plainly:

  • ✓ “Cast of In the Heights performing ‘Carnaval del Barrio’ in bright neighborhood costumes”
  • ✓ “Seminole Theatre marquee lit up at dusk with ‘GREASE’ in white letters”
  • ✓ “Charles Benitez directing rehearsal on the main stage”

Bad alt text (avoid):

  • ✗ “Poster” or “Image” or “IMG_3847” (meaningless)
  • ✗ “Click here to buy tickets” (that’s a CTA, not a description)
  • ✗ “In the Heights In the Heights In the Heights Seminole Theatre tickets 2026” (keyword stuffing — Google penalizes this)

Filenames

Rename files before uploading. Descriptive filenames help SEO and admin sanity:

  • ✓ in-the-heights-cast-carnaval.jpg
  • ✓ seminole-theatre-marquee-night.jpg
  • ✗ IMG_3847.jpg or Screenshot 2026-07-20 at 4.54.44 PM.png

07

What NOT to do

Common mistakes that quietly degrade the site.

  • Don’t upload the raw phone photo. Ever. Always crop, resize, compress first.
  • Don’t upload PDFs as images. If you have a show poster as a PDF, export it to JPG at the target dimensions.
  • Don’t use screenshots when a real photo exists. A photo of the actual show is worth more than a screenshot of Instagram.
  • Don’t rely on the “featured image” being cropped correctly. The site displays it landscape (16:9). If the source is portrait, the top and bottom get cut off — with faces or the show title.
  • Don’t upload images with copyright watermarks visible. Getty, Alamy, Shutterstock — these charge if their watermarked previews go live.
  • Don’t upload images larger than 3 MB, even by mistake. The site’s compressor plugin will handle small overages, but 3 MB+ files can time out during upload on slow connections.

Recommended tools

The lightweight kit that covers 100% of what staff need.

Preview (Mac, built-in)
Crop, resize, export as JPG at chosen quality. All done in one panel. Free, no install.
Windows Photos (built-in)
Same capabilities on Windows. Right-click → Edit → Crop / Resize.
Free web tool by Google. Drag an image in, see file size before/after in real time, sliders for quality. Best in-browser compressor.
Free bulk compressor for JPG and PNG. Drop up to 20 images, download the compressed set. Typical 50–80% size reduction with no visible quality loss.
If you need to CREATE the image (make a promo graphic with text and logo), Canva has templates for social/event sizes. Export at 1600 × 900 JPG for direct upload.
