Actually, Brian's suggestion won't really solve your problems nor really
apply. (No offense intended) In both cases you want to physically
manipulate the images. This will require, as Brian mentioned, a utility.
You'll want to look into using either ImageMagik or GD. I've never used
ImageMagik but I have used GD quite a bit. To enable the PHP GD functions,
you'll need to compile PHP with GD support. The more recent versions of GD
support mainly JPEG and PNG image formats. GIF is not supported because it
is copyrighted. If you need GIF support, you might be able to find an older
version. You'll need one that's about a year old. (I believe that's when
they stop supporting it.)
In regards to the second question, you wouldn't even have to store the image
in a database if you just want to manipulate it. You can just manipulate in
on the filesystem.
Hope that answers your questions,
Jason
