[Therion] Size of image files

Is there a limit on the size of image files that Therion will handle, or is it my computer? Importing a 20Mb png image into a Th2 file caused the program to crash on me, giving a little box labelled "Fatal Error in Wish" and saying "Fail to create pixmap with Tk_GetPixmap in ImgPhotoInstanceSetSize." Interestingly the same image imported perfectly OK in a different computer, but with the same amount of RAM. Graham --- graham.mullan@wotcc.org.uk 0117 9502556 or 07887 637064
