Problem #1: Another way to get your pictures to show up is to render the garment (on or off a body-your choice) in another window with dimensions 100 pixels x 100 pixels and save as a .png file. The name of the .png will have to be EXACTLY the same as the pose file. You need to save the .png to the same file as your MAT pose file. (i.e., Program Files/Curious Labs/Poser4/Libraries/pose/"name here". Overwrite the .png file, if any, which already exists under that name. I hope this helps.
