ClickToGif is an extension for Google Chrome. This extension replaces all occurences of GIF images in web pages with a "No GIF" image. Each occurence of the No GIF image can be clicked to reveal the original GIF. The extension also supports showing all replaced images and whitelisting pages.
By default, the extension blocks all GIFs on all pages. After a page has loaded, the extension waits two seconds and then replaces any found GIF images.
If a page is not whitelisted, a URL bar button will be present. This button can be clicked to show a menu with two options:
- "Show All": shows all original images on the page
- "Whitelist Site": adds the current web site to the whitelist
Note: the whitelist must be enabled via the extension settings before it will take effect.
The "Save Options" button must be pressed before any changes will be committed.
The "Delay Time" setting adjusts how long, in seconds, the extension will wait after a page has loaded before processing it for GIFs. This value ranges from 0 to 15 seconds; it defaults to 2 seconds.
The "Deep Scan" setting enables, or disables (the default), a more robust scanning method. The default scanning method simply looks for
img elements with a
src value ending in ".gif". Enabling the deep scan will cause the extension to download the first 64 bytes of each
img in the page to verify the image header. This is useful on sites like Google+ where all
img elements claim to be JPEG files.
This setting is either enabled for all pages or disabled for all pages. The nature of this setting means extra bandwidth will be used and extra processing time. Thus, you should only enable this setting if you are seeing GIFs when you know the extension should be hiding them.
The "Enable Whitelist" setting turns on whitelisting for the extension. Any site added to the whitelist will not be parsed by the extension. Sites can be added to the whitelist via the form shown in the options after enabling the whitelist, or via the URL bar button menu.
The algorithm used by the whitelist is very simple: if the URL being requested matches any item in the whitelist then the extension will not parse that page (not even the URL bar button will be shown). For example, if you have "example.com" in your whitelist, then "http://foo.example.com/index.html" and "http://example.com/foo/index.html" are considered whitelisted.
