I'm building a image sharing site and would like to know the pros and cons of resizing images on the fly with php and having the resized images stored.

Which is faster?

Which is more reliable?

how big is the gap between the two methods in speed and performance?

Please note that either way the images go through a PHP script for statistics like views or if hotlinking is allow etc... so is not like it will be a direct link for images if i opt to store the resize images.

I'll appreciated your comments or any helpful links on the subject, Thanks.
