I decide on each image separately .. depending on what I feel I want to emphasize, for instance my last image was placed in the Poser gallery .. I did so with this particular image because I wanted to feature as specific model .. I very much liked the model and wanted to show her off were there would be the most interest in her. Technically I suppose it should have gone in mixed medium .. I painted the cloths and the background is Bryce .. Sometimes there are parts of the image that I think would be of interest to both the Bryce and Poser set.. if say I want to discuss a technique is of interest to those in Bryce, then I post an over all image in Bryce .. if that image also contains a character or technique that I think would be of interest to the Poser crowed then I also post a detail portion of the image to the Poser gallery .. for me it is a personal decision based on what I consider to be the area of interest in that particular image.
