php and png

[VaaKo]

how can I write to a picture (png) through a php file ???
I have a signature, and I wrote a text one it, but I wanna change it daily, and I don't wanna edit the image through photoshop and upload it again... it'll be a pain...

how can I edit the text through the php ?

You'd need to make use of either imagemagick or gd to do that.

I'm no phpcoder

but you can try looking at php.net and search for gd functions :)
