To my knowledge, there is no way to make a jpeg transparent. Use png instead (if Therion support this format...)

Hi All
Michael and I are putting some large scanned map-images on our therion pdf plots, but near the point where they overlap, one always overwrites the other.  We’d rather they be transparent so one map-image can be seen through the other.
 
Will it help if I can figure out how to make the white background of the original scans transparent?
 
Does anyone have any tips for making the white area of a jpg or pdf image transparent?  I have access to Adobe Elements, but I’m not very good with it, and although there are instructions for doing this I didn’t have much luck comprehending what was required.
 
Regards
Bruce
