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. ___________ Eric Hodges	[reply]

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)} );` [download]	[reply] [d/l]

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.	[reply]
