CGI, stdin, image handling

[Richard Miller]

Mark,

I'm not quite sure what you're suggesting. I have no control of the  
files before they are uploaded through a browser. These files could  
come from any user.  Are you suggesting to take the data that comes  
in through the Rev CGI and use base64decode on it before saving it?

The other route I've been pursuing is to use a PHP-based file upload  
script to bring the files into the server. There are dozens of those  
scripts and they all work fine. The problem I have is that these  
scripts simply upload a file to a given directory and store it, but  
provide no means to identify the source of the file. In my case, for  
each JPEG that comes in, those images are associated with specific  
records in my database. I haven't figured out how to identify which  
record any given JPEG is associated with. Seems that none of these  
PHP scripts provide for a way to capture additional information on  
the uploaded images. They just store file under its original file  
name. This process would be much easier if I could get the Rev CGI to  
pull in the image files.

Thanks.
Richard
