Actually - we should have a mixed application section. That would solve everyone's woes. Mixed Medium is too...confusing, as medium can mean different things. Mixed applications is more specific and would cover every situation in digitally created works accross multiple applications  I think.

Out of curiosity - if I render in Poser, export the image as a PSD and then save from Photoshop as JPEG before posting because I like the "save for web" feature, does that make it a Photoshop image?
