Seed of the random images

Hello, sorry for being annoying.

When I create an image with the create option/button on this page there are two options: use a specific seed or a random one.

I would like it to appear in the output images which random seed was used, so I can use that seed if I liked the result.

Another thing, can you evolve the created images or load an image from the PC as a starting point? I don't know the answer and I don't see any forum to ask.

Thanks in advance.
