Refresh image and portion of webpage

[fib_81]

Hi Everyone,

Is there a way to refresh a portion of webpage? What I am trying to do is I want to query the database every three seconds or so for value x and if value x is True then I show a different image. Is that possible?

Thanks

One way is that you could have an hidden iframe with a referesh meta tag in it that does the database query, and have it write a piece of javascript that changes the image when it needs to.

Thanks Dijkgraaf. I did some web searching and iframes seems to be the preferred solution. Thanks again.
