RE: [PHP] Advanced maths help (part 2)

Hi Trevor, Sorry, am just a bit confused myself mostly because I am using a third party script to clip the 120x90 part out of the image...understanding the way the script is written is a little frustrating as it was written for something else and I am trying to adopt it. if you want to try your hand at it tell me and i'll zip up the script and send it to you.
