IIRC, Poser converts & handles everything as "uncompressed" bitmaps, so the processing speed and resource usage is a function of the image dimensions in pixels. Compression (re 200K filesize comment) only affects original download speed, and loading time, not actual memory resources once in Poser. (Uh, does that sound right?) I would suggest using the file sizes and standards used by Staale in setting a quality benchmark.
