So, from my understanding, they are really just text files that are interpreted by another application in order to create a visual image.My question is this:Since they ane just text files anyways, why are they *not* include-able with WebCatalog just like any other text file? I'm not asking why they cannot be *displayed* as an image ... I'm asking why the characters that comprise the data in the data fork get changed when it's included by WebCatalog?Isn't [include file=some.gif&raw=T] supposed to include the data in it's raw form -- exactly as it occurs in that file? Or is there something else going on here that I'm mising ...Perhaps the data in the .gif file is not really what it appears? Maybe it's a different form of data that WebCatalog cannot include without changing the character representation of this data?I don't know the asnwer here, that's why I'm asking -- but if my ideas here are not the problem, then why doesn't the raw=T parameter make WebCatalog include the data as is?Sincerely, Ken Grome 808-737-6499 WebDNA Solutions mailto:ken@webdna.net http://www.webdna.net
