urgent fix cashing php script - simple

Hi We have a thumbnial script that call a thumbnail service yet we do have error there and we cashing error messages from thumbnail by mistake we need to or you need to stop cashing all error message from the [login to view URL] I can let u login to account to see all error messages they send Here what thumbnail provider said: " When I go to those pages we are not receiving new requests from you. Since it appears that you are caching your images locally, this means that you are simply displaying your error message images instead of making the request again now that your account has been upgraded. Best Regards," "Hi You SHOULD use a script for caching locally. It is THE best way to use our service. However, your script must be sure not to "cache" the error images. Our sample code provided ignores any error images, so if you used that then there may be another reason. But, in any case, Frank told you the right way to do it. It's just something is a little quirky somewhere in the "caching logic", it would seem. It is probably a relatively easy fix, if you take a look at that part of the code. - So we need to fix that here sample erros: [login to view URL] [login to view URL] see script attached We need it quick Thx!
