I have just one short question:
"How can i store single texels in an efficient way in Compute Shaders?"
The performance of the function imageStore is really bad, so how can i increase that?

I know that SSBOs could be an alternative way to deal with this problem, but i would
really prefer to stay with image textures.

On my GPU, the imageStore function halfs the performance of the compute shader. That
is not really what i want!

Hope someone can help me!
