Is it possible to use the GD Library with actual images?

I'd like to use the GD Library with actual images - BLOBs f开发者_高级运维rom a mysql database.

Can it be done? If so, how?

Thanks.

Yes, using imagecreatefromstring().

It accepts an image as string data, auto-detects its type (as long as it's supported of course) and creates a GD resource based on it.
