ok, I've been able to fix it.
In the file
/modules/TDMPicture/templates/blocks/tdmpicture_minitable.html
line 39 reads as <{$xoops_url}>/modules/TDMPicture/images/demo.png"
It should be changed to
"<{$xoops_url}>/modules/TDMPicture/images/min_demo.png"
I noticed on sourceforge that the most recent version has the same error and it should be fixed
