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

Yes, sorry I didn't phrase my post very well: there is a URL for the image,
of course, but I was trying to emphasise that there isn't a URL to an image
cached on the server's filesystem to pass back, as I don't want to
*permanently* cache the image (or implement a cleverer algorithm - there's

Christof,
Thanks for that, but I was really looking to see if there was a
browser-independent mechanism, essentially something like the Web archives
that IE has supported for years. I think adding components for this would be
over-complicating the matter.
Thanks anyway.

No, there isn't. Canvas and IECanvas is the closest you can get. I have done
quite some research on that matter for a project where I really could have
profited from canvas, but IECanvas was
I never noticed that they ever were browser-independent.
I know, that's why I said 'that IE has supported for years' and why I can't
use them.
Despite the ways there are to do this such as these canvas projects or
something big and bulky client-side (Java, Flash possibly, any number of
similar

Hi,
I believe the ctx variable should be:
var ctx = $('canvas')[0].getContext(2d);
I was expecting that a canvas tag exists on the page. If it doesn't it should
better be something like this:
var ctx = $('canvas').appendto('body')[0].getContext(2d);

JK,
Thanks but no - that's my alternative.
Dan,
Absolutely, please do tell me if I am!
I have a server-side script which generates a graph image given a set of
dataset identifiers. Additional datasets are implicitly added server-side
too.
Currently the image contains the legend, but I'd like to

Hi,

dataset identifiers. Additional datasets are implicitly added server-side

Currently the image contains the legend, but I'd like to generate the
legend in HTML as it'll be more consistent with legends used for
Rob,
I have a feeling the answer is a flat 'no', but want to check: is it
possible for an AJAX request to retrieve binary image data (e.g. raw
GIF) and display that on the page?
Can you describe the *exact* effect your trying to achieve?
Why do you think you need to load binary image data via
