Re: Re: Item not refreshing with the page

I've seen images refuse to refresh even when the rest of the page was. If this still happens, try somethng like:

$dummy = rand(1000);
print "<center><img src=\"test.png?x=$dummy\"></center>";
[download]

to convince the browser (and any intermediate caching things) that the image is in fact query.

Your code is engenius, it really is. That totally fools the browser into thinking it's something it can't cache and it worked. That's utterly amazing, thank you for this tip! And thank you to the others. I didn't know an image will stay in cache as long as the name and size doesn't change. I just thought it reloaded the image if it realizes the page has been updated since the last time it's visited. Thanks for that information.

I can't claim credit for originating this - I got the idea from a list or a newsgroup when I was fighting a similar issue - glad it helped. --Bob Niederman, http://bob-n.com All code given here is UNTESTED unless otherwise stated.	[reply]
