Re^2: CGI: Raw image data

[Sprad]

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.

I demonstrate how to embed images into a CGI response in one of my columns.

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">

[jhourcle]

I'd actually suggest using PATH_INFO to pass around the parameters, as it makes it more likely that browsers will cache it, and not attempt to resubmit, because they see a QUERY_STRING, and shut off caching. (You can also send cache-control headers).

And don't forget your ALT attribute:

printf( '<img src="%s/%s" alt="%s" width="%i" height="%i" />',
    $cgi_url, @image{qw(id description width height)} );

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.
