You will have to use the GD functions. I don't know much about these myself, but you could look at www.php.net.

I know Okki (I hope it's spelt like that) is very good with gd.

Sorry, My knowledge goes as far as knowing it is called gd :D

I should look in to it more...

GD is the image manipulation php module. U shoulddownload the php manual (about 16 megs pdf file) and take a look. The gd functions are not hard to use. Good luck!

GD (generally bundled image libraries available from boutell.com) handles writing text over images quite competently, especially in newer builds - anti-aliases on truecolour ping files since 2.0.5 or so.

Your GD build (if you have it) should be compiled with the truetype libraries available from freetype.org - else you will be restricted to using system fonts and imagestring() which just doesn't quite have the ooompppfh

the GD libraries process all image rendering by converting the image to a format called .gd (or .gd2 in newer builds)
which is quite resource hungry.
therefore - dynamically creating images at every page load is something to avoid like the proverbial. If you can, preprocess any images and save a server copy somewhere and just link to that.
failing that - perhaps preprocess the background image and save it as .gd2 or .gd which, though larger filesize than most public formats, will speed up the scripts and lower the resources used.

if you have tested your php build and have GD compiled
phpinfo(); or
and want a test script, just ask.
