Highlights .gif files in gallery view by adding a glow around the thumbnail. Customizable settings are shown in the right sidebar, under the petition rename/expunge links.
Got tired of hunting around galleries for the .gif files, so I made this.
Simple jQuery Tampermonkey userscript that highlights .gif files in a gallery with a glow around the thumbnail.
Feel free to adopt this code for your own use.
Updates to code for the change in gallery HTML, plus added highlighting for .webp (with a toggle)
Once you're done choosing your color/size, you can edit the script and UNcomment out line 32 to hide the setting link if you don't want to see it anymore.
You can adjust the colors/size of the glow using the WG_GLOW_SIZE and WG_GLOW_COLOR variables near the top.
WG_GLOW_SIZE accepts any number
WG_GLOW_COLOR accepts colors in either color name format ("aqua", "orange", etc.) or hex format (#00FFFF, etc).
