GD Library help

[alyson]

I know this is a somewhat broad question, but I have three things I would like to know how to do with php + GD Library.

1. Layer images on top of each other (like this generator: http://kawaiiness.com/buttonmaker/)
2. Create a text mask with a transparent background (Like this: http://www.phpbuilder.com/columns/cash20030526.php3?page=5 except without the black background there)
3. Creating an upload image form and use it as part of a dynamic image??

Thanks in advance  :)

Best way still is the PHP manual chapter on GD image functions. See
