Force a photo to reload

[minifairy]

is there a way to force the browser to re-load a photo.

I have a program that will replace a photo. It uses the existing filename and writes the new photo over the old photo.

Then it uses the header function to go back to the edit page. Most of the time the old photo will still show there.
How can I force the browser to reload the photo so it will get the new photo?

If the photo is displayed in an IMG tag, you could use javascript to do it. If it's just an image loaded in a browser, I don't think it's possible.

One way might be to use some [man]header/man calls on the edit page to (try to) force the browser to ignore its cached version and instead re-retrieve all elements on the page.

Another option might be to output some random garbage in the query string in order to make the browser that the resource is constantly changing, e.g.:

<img src="/myimage.jpg?20120130-this-text-is-meaningless">

I think the best way would be to use an AJAX callback to refresh the container.
Probably not the easiest way, but most expandable.

Thanks everyone. I'll give it a go and see if I can get the simple idea to work.
