I don't see where there are "hairs" to be split here. Its all very straightforward and obvious. The programs a artist uses to generate forms are their MEDIUM. Ultrafractal is A MEDIUM - Poser is A MEDIUM - a camera is A MEDIUM - Bryce is A MEDIUM when PSP is used to generate a tube or form, it is a MEDIUM. Just as paint is a medium separate from pen and ink or granite and marble for sculptors. Use Ultrafractal and Poser to make an image, and you have TWO and therefore, MIXED media. Use Xenodream and Terragen and you have mixed/multiple media used and so forth. However, I don't think it should be disallowed if two FRACTAL media, say Ultrafractal and Xenodream or FE or whatever are used - they are both fractal media and this is a fractal gallery. I don't think its a problem moving things to other galleries; why bother unless you are one of those that has images in the "most" pages - who looks back to page 100 of any gallery, anyhow? I would imagine this stuff would affect new postings mostly.
