Re: Resize Image On Save is resizing all images in directory?

After a bit more debugging I have found that when the save method gets
called it loops through every record in the UserProfilePic table so
that is why
the self.profilepic.path gets assigned eg image1.jpg, image2.jpg and
when doing a resize it loops over them all opening each path from the
table reszing each image.

Can anyone explain why this works like that?
