I must have changed the code at some stage its a few years old it was written for a specific purpose but I dont use it now. The file_ref is the name of a txt file which contains the slide names you could just create a list (setq Pts_lst '(dwg1 dwg2 dwg3 dwg4)) and remove the un-necessary code to read a file. It was done that way so it could be given to someone else who put their own slide names in the text file and not have to fiddle with code.
I want to change the image when it is active when going through another edit_box edit_box to show my other imagime as possible that ,I do not need edit_list
