Why Your Photography Website Is Slow (and What It Costs You)

The scale of the problem

A typical business website ships around two megabytes per page. A photography gallery page routinely ships thirty to fifty, and occasionally far more. That is not a small difference in degree. It is a different category of website.

The cause is nearly always the same: images exported at full resolution from Lightroom, uploaded directly, served at their original dimensions and scaled down by the browser. A four megabyte, 6000 pixel wide file is being displayed in an 800 pixel box, and the visitor downloads every byte.

What it actually costs

• Rankings. Page experience signals are part of how Google ranks. Slow gallery pages underperform faster competitors with weaker work.
• Visitors, immediately. Bounce rates climb sharply past three seconds. At eight seconds on mobile, a large share of visitors leave before seeing a single photograph.
• Crawl efficiency. Slow sites get crawled less thoroughly, so new pages take longer to index.
• The mobile reality. Most of your traffic is on a phone, frequently on patchy signal. Your fast office broadband is not the test.

The target

Largest Contentful Paint under 2.5 seconds on mobile. This is achievable for almost any photography site without changing the design, purely through how images are handled.

The fixes, in order of impact

1. Export at sensible dimensions

Nothing on a website needs to be 6000 pixels wide. For full width hero images, 2000 pixels is generous. For gallery images displayed at 800 pixels, export at 1600 to cover high density screens and stop there. This one change frequently halves total page weight.

2. Use modern formats

WebP typically cuts file size by 25 to 35 percent against JPEG at visually identical quality. AVIF goes further. Most platforms now support automatic conversion, and where they do not, converting before upload works fine.

3. Compress properly

Photographers resist this, understandably. But quality 80 on a well exported JPEG is visually indistinguishable from quality 100 at screen sizes, at roughly half the file size. Test it yourself on your own work before deciding.

4. Lazy load everything below the fold

Images further down the page should load as the visitor approaches them. Critically, the hero image should not be lazy loaded, since that delays exactly the thing you want to appear instantly.

5. Shorten your galleries

Sixty images on one page serves almost nobody. Visitors rarely reach the end and the weight is enormous. Twenty to thirty strong images, or pagination, performs better on both counts.

6. Set explicit dimensions

Width and height attributes stop the layout jumping as images load. This is a ranking signal and, more importantly, one of the most irritating experiences on the mobile web.

Platform reality

WordPress gives you the most control and the most ways to get it wrong. Squarespace and Showit handle some optimisation automatically but limit how far you can go. On every platform, correct export sizes and disciplined gallery length are within your control and deliver most of the available gain.

Where to start today

Run your busiest gallery page through PageSpeed Insights on mobile. If Largest Contentful Paint is over four seconds, re-export that page’s images at half their current dimensions and measure again. For most photographers that single change is the largest speed improvement available.
