Image Mod
Site-wide master for image previews on public download pages. Default on. Tiers still need Show image mode.
Image Mod
Site-wide master for image previews on public download pages. When off, image preview URLs are blocked and Users limits Show image mode has no effect.
Where to find it
Admin → Settings → Mods → Image previews → Image Mod
Setting key: toggle.image_mod
Default: on (unset = enabled)
How it works
Preview shows only when: this mod is on, the viewer's tier allows Show image mode, the file is an image, and password/premium gates pass. Resize mode (next article) controls how the image is served.
Common problems
Mod on but guests see no preview
Users limits → Show image mode off for that tier, or the file is not an image.
