Topic: Script development / Listen for new images

How can I listen to tell when new images are shown on a page using AJAX? Is there a way to detect changes in the DOM?

Also, is it possible to tell whether I have already added an event listener to a specific image?

I know this site is primarily for Firefox... but have you considered using Opera? You could set it to only load cached images and if you want to see an image you could load it through the context menu. You can also disable plugins like flash etc, and selectively enable it for certain sites only.

I know it's been a while since you requested, but I wrote a script to do this which you can get at http://userscripts.org/scripts/show/21143

You should probably take a look at the number of people using the script and be sure to read comments and see what other people thought about the script. By looking at the dates of the comments and the date that the script was last updated you may also be able to get an idea of how long the script has been around (older might mean better).

Also, when installing a script you should see a list of the sites that the script will run on. Make sure it is only set to run on the sites it's supposed to run on. (If it's just a * that means it will run on all sites)

If you eventually learn Javascript you could take a look at the code before installing, but honestly I don't think I've ever done that even though I know Javascript well enough to submit my own scripts. I just try to look at the stuff I mentioned above, and I don't install too many scripts either.
