Quick question here. I wanted a way to quickly change the URL of an image that is place on my page, so I came up with the following little script:
I pass the $status variable from a link before this page.
It works the first time. Actually it works all the time, but after the first time, the old image is left in the users temp directory, so the image doesn't change until they delete it from their temporary internet files. In firefox, it works ok if you just refresh the page, but in IE, it doesn't work until you delete the temp files. is there another way i can go about this?
Let's assume that I can't change the code on the page that is calling the image. That's why I need to change the name of the file on the server.
Thanks.

Use the above code to tell the browser not to cache the page.

So you're saying that code needs to go on the page that I'm displaying the image on? Little problem with that, can't use php. Only html. I can run the php script from anywhere, the page that's calling the image hast to be plain html. So can I implement that solution without the php?

Ah, I see, instead of sending the headers via php, put them where they ought to be in the first place? Thanks for not laughing in my face. That should do it, I'll give that a try.

Well, I tried putting this in the <head> tags of the page:
<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">
As well as this:
<META http-equiv="Pragma" content="no-cache">
And it's still having the same problem.
Any ideas? Sorry, I guess this is now turning into an HTML discussion, of which I am even less experienced with than PHP, but that's another story!

hmm.. well, i am kinda lost too. But, If you can use javascript, try location.href="status.html". Some other alternatives (?). Try
<META HTTP-EQUIV="EXPIRES"
CONTENT="Mon, 22 Jul 2002 11:12:01 GMT"> or, you can redirect to another page, say, page1.html and then, redirect back to status.html.
If no-cache doesn't work, then i don't know what will ?
