CGI, stdin, image handling

[Richard Miller]

Brian,

This is the header:

-----------------------------22007350812635
Content-Disposition: form-data; name="upfile"; filename="we10_1.jpg"
Content-Type: image/jpeg


I used "binfile" and have been using a Rev script to discard the  
header and end data. I am reading directly from the .jpg file into a  
variable in Rev and doing all the processing in that variable before  
writing it to a new .jpg file. Still, there are some "funky"  
characters appearing throughout the file.. something on the order of  
30 bytes in a 12k file (and they are there before I do anything in Rev).

Thanks.
Richard
