Php jpgs getting corrupted

hey everyone,

i created an upload script to upload jpgs on my local network. i store the filename into a database. i then read the database for all the jpgs filenames, and create links from them. however, they look corrupted when i view them through IE.

when i view them this way:
http://localhost/lwsp/imageviewer.php?image=portfolio_img/_wd_01_2.jpg
the image looks corrupted

when i open the same file in ps7 or other image programs, they look fine.

anyone ever encounter this problem?
