Still with the pics!

I've posted before and abonded the issue. However.... It's really crunch time.
I am still having images apear on the wrong product. Can you please write a step by step insctruction so I can get all of this straightened out? If it's possible to write the images via absolute path and also by the GUI upload.

I think my main confusion with all of this is the "production site" and everything hosted on a dot com and the absolute path for the image anmes noted via the 301 .net web address. But even as pictures are uploaded if it doesn't display, it still shows a different img instead of the default no image provided.
Thank you!!!!!!
