in reply to CGI: Raw image data

You can send the raw image data directly to the browser as long as you know the image type. 

use CGI;
my $q = CGI->new;
my $imgdata = get_image_data();
print $q->header( 'image/jpeg' );  # or image/gif, etc.
print $imgdata;

    Don't forget to add 
    binmode STDOUT;

    before you print the image data, just to be safe.

    Can I do that in the middle of a page, though? I actually need to display several of these images on a page, along with some UI and text.

    A fair fight is a sign of poor planning.

      For each image you can make the images URL refer to a CGI like the one he gave you so that each image is a call to the CGI.

        Just to clarify a little bit: 
        <img src="PATH_TO_CGI.cgi?whatever_params_youneed">

      You could use the data: url scheme, but you'll find browser support a little lacking (Internet Explorer is among those browsers without support).

      You'll need to, as previously mentioned, have the user agent make additional requests for each image.
