That'll try to inline the images, which won't work. Exactly.
If you want to create them at the same time, you'll probably have to create a folder with two images in it, and store it somehow. Your external method would want to return the name of the created container. This might be an option here.
The better answer is to make two methods (one for image, one for key) and give both methods the same parameters so they can create images on the same information. I considered this but it would be very bad because I would have to do the same database query twice which would cause quite bad performance.
My second thought was that I do not really need two images because the second image could be replaced by one constant image containing plain colors and returning legend text description combining it with the image in a table - but this causes fiddling around with save placement in different browsers. Moreover this reduces the problem only slightly: Replace return of two images by one image and a touple of text entries.
That won't work if you have non-parameterized controls (random or external), in which case you'll have to figure out some sort of index/snapshot scheme. I'm afraid I do not understand this sentence.
Kind regards Andreas.
