Re: [PHP] Drawing Images Without Writing To a File

Ken,
	That's exactly what I want and it works beautifully!  I wish I had asked this question a long time ago since, in the past, I have been creating the files and wind up with a bunch of image files hanging around.  When building this new site I thought there must be a better way!

Thanks!
Floyd

Is it possible to generate the image and send the data back and make the browser think it's loading an image file?  I know this can be done by sending the proper headers back for an entire page, but I just want to do basically the same thing for just part of the page.
