Welcome to this forum.
If you would bring the problem down to a small code example instead of putting your assigment here you might learn something from it. Attaching files isn’t also the best approach.
Best you make an example/expert of the part of the code that doesn’t work and next you "copy compress" and paste it along with your question.
In my set up the images are not shown at all. It looks like the images are not applied as textures. Could you bring the example down to an example without the audio, camera’s and attrui objects. This way you’ll isolate the problem more. Without these objects you also could drop the [patcher] objects for maximum for debugging overview
[jit.gl.videoplane <drawto>] The argument is not a texture name! The whole-drumset picture is displayed by accident – you put here a name of your jit.window. In your case (and if you use max6) I would do away with this argument. Also, [jit.gl.texture]s are redundant with videoplanes.
