RE: [PHP] sample code snippets writing text to images?

Thanks for the example, Thiago. This raises another question, however. I noticed that the code below sends the header after the HTML tag, which (if I understand correctly) requires a special setting in the php.ini file. Assuming I don't have access to that file, is there a way to work around this or to toggle that setting on a page-by-page basis?
