I found that sometimes an image won't load fully on my browser, and when I press F5, instead of refetching the image from the server, the browser reloads it from the cache. Is there anyway to force the server to resend the image?
Edit: I am using Google Chrome.
Note: But I am speaking here as an end Internet user, not as a developer. So the idea to modify the HTML to put in a random number doesn't work here.
On many browsers, pressing Control-F5 will reload the page and bypass the cache. The Wikipedia "Bypass your cache" page has details for all modern web browsers.
For Chrome, it appears that as of this writing there is a confirmed bug where it will sometimes not bypass cache when reloading with Ctrl+F5 as it is documented. The only option for now is to clear the cache completely, then reload the page. Here's some discussion of the issue: http://code.google.com/p/chromium/issues/detail?id=603
What I've done when the wrong image gets cached is select 'View Image' or the like so I get a page/tab/window with just the image and then shift-reload that guaranteeing that particular image gets reloaded.
