how does raw image data get you anything? Seems you want the data and the image URL via XHR and then dynamically insert your DOM bits (img tag w/ URL from response with some sort of wrapper containing your legend)... I mean, what you are talking about is technically doable (not in all browsers) http://www.kryogenix.org/days/2003/10/18/embedding but I am not sure it gets you anything.
No, you haven't read my post carefully enough. I don't want the image's URL because the image *doesn't have* a URL - it's generated by a server-side script. Because I can't retrieve raw image data and legend data in the same request, this now necessitates 2 requests, both of which have common functionality. This to me seems a little odd that two aspects of the same set of information have to be retrieved separately, but then Web development can be like that sometimes ;-)

because that is just sick! Taking your idea to the next demented level
Absolutely, I've seen that before, hence I was pretty sure this couldn't be done. What a horrific 'solution'! Although I'm not sure what you think is demented about the idea generically (disgusting 1x1 celled tables aside I mean) - many people have a need of embedding raw image data directly into a Web page, exemplified by the first post mentioning people who are willing to pay money for Web archives - MHTs - to be implemented in Mozilla. Email clients support these archives by using the multipart MIME types. So why not Web browsers? Anyway, as I thought it seems there's no cross-platform mechanism for achieving this, so it's down to making sure 2 similar requests don't unnecessarily repeat redundant code. Thanks for your input on this everyone :-) --rob On 7/24/07, Christof Donat <[EMAIL PROTECTED]> wrote:

I guess you are lokking for something like <canvas>. Firefox and Safari do support it. I am not shure about Opera, but IE and Konqueror don't. For IE there is at least IECanvas (http://sourceforge.net/projects/iecanvas), which might be of use. You can use JavaScript to put an Image on a canvas and you also have drawing primitives to add Information. Christof
