Problem in custom painting_dyn

[DRedshot]

For question 1, you need to click on the body covering the painting, click the last tab on the right, and click the 'Su' (attach Submesh) button, then click Attach. Now click on the picture frame and click done! The picture frame should now be attached to the body.

I don't understand question 2, sorry. So you want to rename the actual painting and the frame? I don't think you can without opening them in Maya/Blender/3ds and editing the Object name.
