Item detail page eagerly downloads full-resolution originals instead of thumbnails

Homebox Version

What is the issue you are experiencing?

The item detail page photo section downloads the full-resolution original image for every photo on page load, instead of the WebP thumbnail that HomeBox already generates. On a self-hosted instance with a constrained uplink this makes the detail page slow and wastes bandwidth.

The item list/grid page correctly uses thumbnails — only the detail page is affected.

How can the maintainer reproduce the issue?

Root cause

frontend/pages/item/[id]/index.vue renders each photo in the grid as:

<picture>
  <source :srcset="img.originalSrc" :type="img.originalType" />
  <img class="max-h-[200px] rounded" :src="img.thumbnailSrc" alt="attachment image" />
</picture>
