Your browser is cacheing the image. One easy way to get around this is to append something to the image URL such as "?v=101", "?v=102", etc. where the number is a version # you track on each image.

E.g.:

• http://mysite.com/image.jpg?v=101
• http://mysite.com/image.jpg?v=102
• http://mysite.com/image.jpg?v=103
• ...

Or:

• http://mysite.com/imagegen.php?name=foo&v=101
• http://mysite.com/imagegen.php?name=foo&v=102
• http://mysite.com/imagegen.php?name=foo&v=103
• ...

You don't have to look at the version number in your code, but its presence on the URL makes the browser think it's a different resource and therefore load it again without having to refresh.
