image resizing

[Delcypher]

hi, i need help with opening a image on my server, resizing it and then saving it. I was told by a friend of mine to use the imagecopyresize() function but i couldnt get it to work, because i didnt understand what all the variables it need were.

imagecopyresized ( resource dst_im, resource src_im, int dstX, int dstY, int srcX, int srcY, int dstW, int dstH, int srcW, int srcH)

the resource destination and source , i think are variables, that have been previously set, i understand W and H is width and height but whats X and Y?

This function is designed to grab a portion of an image, starting at 0,0 (IIRC) so the X/Y would likely outline the bottom right area?

so if wanted it to grap the whole image, and resize to say width= 500 and height= 600, what would the code be.
