Someone else is putting gifs in their macros, can I block the image

Flashing pictures are very problematic for me. I don't want to ask this person to remove the images from his macros, he's having fun his way. If I can make an option to ignore them I'd like to though.

Look into it at the Browser level. There's definitely Ad-Blockers --- like, "Ad Blocker" --- that can install on Firefox/Chrome that lets you click an image and block that image, with the choice to block all images from that site (probably just a couple common sources like imgur GIF's would catch em all?). There might also be browser-wide GIF blockers or GIF stoppers (not sure of that). These are usually called/found as Add-Ons or Extensions in FF or Chrome. There might even be (oughta be) a built-in Browser accessibility setting to allow animations or not. (Not sure). As for Roll20 there IS a setting for the GM to disable or enable GIF animations on the tabletop, but it happens to not affect GIF's in Macros in the chat window anyway. Other than that I don't think there is any setting in Roll20 to stop animations, if there is then hopefully someone else will know and answer this.

I fiddled with this for a while in Stylus. I can block the use of roll templates in chat, but not images. It must be possible, but my css chops are not strong enough.

The Ghostery chrome extension is an ad blocker that definitely blocks them.

This should work. Thanks to an anonymous CSS wizard benefactor: Use the Stylus extension as detailed in the top post of  Show Off Your Style , or  Show Off Your Style 2: The Stylening!    Create the following style, called "No GIFs" (for example). #rightsidebar img[src*=".gif" ] {     display: none; } This should cause any image in the right sidebar that is a .gif file to not display. AFAIK, Roll20 does not use gifs anywhere in their interface, so there should not be a conflict with any existing functionality. This will also only affect the display on your local browser, so no one else need even know you are editing out the images.
