png files. I have installed tkImg 1.3... I am running gentoo on an AMD64. Any suggestions? How can I test that tkImg is really working?

Run wish and try following commands: package require Img image create photo -file /path/image.png If it will not generate error, then tkImg is OK.

I havent gotten it to work on any other versions of therion.

Currently, I can not see "package require Img" command in xtherion script. May be, you should add it manually to xtherion script or your xtherion.ini. I am not sure, may it it should be "package require tkImg". S.
