Create Image Object From Binary Data?

Im trying to implement dynamic images on my site. Basically, there is a list box, and when the user selects an option, it calls a service that streams back a base64 encoded image that will be the preview of what they're looking at.in FF you can do this: img.src = "data:image/png;base64," + args ; This doesnt work for IE. from what ive learned, IE doesnt support this type of inline coding.

I was thinking that maybe the next best solution would be to convert the base64 back into binary, and set the new image object to that source. something like this:

Code:

var img = new image();
img.source = binarydata;

now obviously, img.source isnt a real method. but i would like to be ale to set the binary data as the image.

possiblities: Is there anyway to save that binary as a file on the client? and then be able to reference that file as the picture img.src = "images/" + newfilename;

Some other alternatives is to stream back a reference on the server to get the picture, this would require two callbacks, which i dont want.

Also, there is a method of turning the image into a big array of HTMl elements, and each element holds a color, being a pixel. im not doing that, that is the biggest hack job i have ever seen.
