Now, I'm opening a different can of worms, but how do you suggest sending an image file from the database without using send_data, or does send_data not suffer from the same issues as send_file?
I tried using X-Sendfile and ran into issues that files weren't being pulled out of the DB correctly. (Probably should be able to fix this now, after I figured it out) On 9/1/07, Zed A.
