    Distort image, PHP and GD

    I want to distort an image so that you can kind of see what it is but not really.

    Any way of doing this with php and gd?

    let's say you start with some arbitrary jpeg image. you could:
    1) make a gd image resource from it, using imagecreatefromjpeg()
    2) make a blank image resource using imagecreatetruecolor()
    3) use imagecopyresized() to copy chunks of the original

    this would make a copy of the image. now you need to apply some kind of transformation to it, by way of altering the parameters you pass to imagecopyresized(). let's say you wanted to stretch the image, you would make the blank canvas have 2x width of the original. then you would copy from (0,0,w,h) to (0,0,2*w, 2*h).
