Re: [PHP] Image Rendering/Generation Options

Well, you can't output HTML *and* an image in the same request. What you
can do is generate HTML in one script, put image tags in the HTML that
references a another script, which actually outputs the image.

So something like:

<img src="/myimage.php?id=4" width="10" height="30" />

Then in myimage.php you would output the correct headers (such as
"Content-Type: image/gif" for example) and output the raw binary data
that makes up the image.

You can probably glean a lot of useful information from the GD portion
of the manual:
