Guest -- We have changed the EXIF handling in the competition system.
When the EXIF data is tripped from the entry the image is not re-compressed thus there is no loss of image quality from what you upload.
It also means the EXIF we store behind the scenes is more comprehensive.
We are using 'jhead' http://www.sentex.net/~mwandel/jhead/
EDIT: We are also trailing personalised thread titles and text.
They obviously work!
