I'm a web developer and I built this extension to quickly toggle the display of images on and off using a simple toolbar button. I mainly use it for checking how HTML-based emails will look in email clients that don't load images by default, but it would also be useful for any site where you don't want to load images.
The toolbar button clearly shows the current state of the setting by changing the image (see screenshots). The current setting is also remembered between browser sessions and updated when a site is loaded, handy for those sites you visit regularly but don't want to see the adverts!
The extension works on http://, https:// and file:/// URLs but you may need to enabled file access if you need it (Tools > Extensions > expand ImageX > check "Allow access to file URLs").
During installation ImageX will request access to:
• Your data on all websites
• Yours tabs and browsing activity
The first is needed so that requests to file:/// resources can be handled (see above note about enabling file access).
The second is needed so that ImageX can updated whenever the current tab is changed or updated.
The third is needed to retrieve and update the Images Content Setting (see Settings > Under the Bonnet > Privacy > Content Settings... > Images > Manage Exceptions...)
PRIVACY STATEMENT: This extension uses Google Analytics to record when the tool is used. No personal information or URLs are tracked. This is satisfy my curiosity as a web developer about using Google Analytics and see if my extension is being used by anyone.
