i posted a pic of my daughter here and at flickr. why is it that the one posted at flickr sharper than the one i posted here? or is it just me?

the forum/gallery has a built in photo app that will reduce the image quality to whatever the administrator set it too. thus, it's set lower than what is on flickr. :)

GD and ImageMagick is what most forums/galleries use

ahhh, thanks for the answer john. :)

Updated image compression quality for the Gallery for thumbnails.
