ChromeOverlay

ChromeOverlay is an extension that lets you create a .GIF or image overlay on every webpage you open in Chrome. All you need is the link to an online image or GIF and it'll show up on top of your page!

You can adjust the image transparency and set favorite GIF links for easier access.

Now with support for .mp4 and .webm files! These files won't load on certain sites that have Content Security Policy blocking loading of video content, but should work on most sites.

options:
disable the image checking this checkbox removes the overlayed image
GIF transparency adjust this slider to change how transparent the overlay is
Load current URL Loads the URL currently being used as the overlay into the textbox. Useful if you've set a GIF without saving it and changed the text
Set as new overlay Set the link from the textbox as the current link to display on the page
Save URL as favorite Adds the link from the textbox as a new favorite

Favorite options

Load URL Loads the favorite URL into the textbox and sets it as the current link
Delete Removes the favorite. Has no effect on the currently loaded link
