well, the previous advice was a shoot in a dark, based on error/image, without looking into code.
after checking code/script, dev has messed up image-names, he used it with"_02" and without it (perhaps he planned to add "_02" image as a different scene, yet there is no such image yet), so based on the script, go back to deleting "_02" from the image, and copy/paste attached script and replace your old one.
hope that helps
btw,
in case of similar errors with other "02" images, open this script file with a text editor, search for that particular image-name and delete "_02" part from the text, save and close the script (before that check if there is no "02" image in the images folder as well).
didnt play it for a while, probably this has been reported already in the past, and probably there is a cumulative fix for all missing images or something, so you can also try and search this thread a bit
