#Php image resize on the fly code#

Is it possible to include some sort of image resize code? if so can anyone point me in the right direction or better still show some example code and explain how it works etc. I have a working image upload script that uploads, renames the file and adds filename to the database. After 1st group of codes resize the picture, is it necessary to save it into folder before I can crop it? If it is necessary, then I need to write new lines of codes to retrieve the resized pic from the folder for 2nd group of codes to crop it? If it is not necessary, after resizing the pic, how do I pass the pic to 2nd group of codes to crop it? 2nd group of codes crop the pic then save it into the folder too.

The problem is they works separately, how to combine this two groups of codes to make them work together?

If you want the original formatted source code, visit the link above.I want to reduce a picture size from 600px * 500px to 60px * 50px size, then crop it become 50px *50px. I reformatted the source code so it's more readable for my own eyes.
