I'm using PM 5 build 15800. I'm using the PM Classic export and would like to use the filename of the exported image as the title of the thumbnails. However I seem to be missing it or it just does not exist. Specifically, I export without using the original filenames for the images so the image files get named IMG_1, IMG_2, etc. I'd like the title for the thumbnails to be the same as the exported image filenames (i.e. IMG_1, IMG_2, etc.). Can this be done?
