Image preview resize mode
Original, Auto (1600x1600), Standard (800x600), or Custom. Non-original modes usually serve WebP.
Image preview resize mode
How image previews are sized on the download page (admin label: Preview resize mode).
Where to find it
Admin → Settings → Mods → Image previews → Preview resize mode
Setting key: image_preview_size_mode
Default: auto
| Value | UI label | Behavior |
|---|---|---|
original |
Original size | Stream stored bytes; no resize box |
auto |
Auto | Fit inside 1600 x 1600 |
standard |
Standard | Fit inside 800 x 600 |
custom |
Custom max size | image_preview_custom_width (default 800, 64-4096) and image_preview_custom_height (default 600, or auto) |
Non-original modes typically serve a WebP preview (aspect preserved, fit inside the box). ICO streams as stored. SVG is rasterized to WebP (not left as SVG).
Common problems
Huge images crush mobile layout
Use Auto or Standard instead of Original.
Blurry custom previews
Custom box too small - raise width/height.
413 on preview
Source image too large for the preview pipeline - lower resize mode or source size.
