Try one of the earlier versions of UVMapper to see if it still dosn't work. Perhaps the latest one dosn't work as well with your OS? I'm on MAC OS 8.1 & the new version of UVMapper seems to work well (only tested one thing so far). Just for the heck-of-it open the pict file in GraphicsConverter & re-save as "web-ready" to omit the resource fork. Also, if it's a huge file you may be having a problem with not enoughe memory, Poser assumes it can't find a file when it runs short.
