this is the photo that caused the error on the profile:  christina

screenshot beow, shows the images size:  I opened it in photoshop and nothing else seemed weird about it.  it was  a JPG and RGB.

Her profile page had a PHP error on it, causing nothign else but the error for her profile:

An error occured in script '/var/www/mercury/core/functions/imageResize.php' on line 46:
imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg, libjpeg: recoverable error: Corrupt JPEG data: 2 extraneous bytes before marker 0xe1

FIX:   I logged in as her, and uploaded a new photo per Dans suggestion.  Fixed for now.

*** would like to have the image re-sizing bit looked at and made to be more user friendly, and/or allow bigger images to be uploaded.

with our move to the image magick library this should be resolved
