I need help with Textures, its like a puzzle? I there an easier way?

First thanks for all the great tools and advise. I utilized your videos and learned very quickley how to upload mesh projects and copy products, however i am having a hard time apply textures, its like a puzzles trying to get textures placed in correct place? Am I missing something? Is there an easier way to do this? Lets use the example of the Scarlet Creative Clessy Manor 1 somone posted. I am having a very hard time figuring out where the textures go now that I have uploded back into SL. Help!  Thanks :Nerd:
