Your image was banned for some reason.
Perhaps a model number would help.
Also a description of what exactly the problems is re: getting it around the idler wheel etc.
Ok thnx for responding I will post model number in a few, I already have new dryer belt on(no problem), but when I put it through the pulley(like 10diff ways) the belt is loose?! Idk why

Here are some belt diagrams.

Yours should look like the Franklin just with the idler on the left not the right.
Using your picture.
Remove belt from idler wheel.
Pull (tension) idler to the left,
Place belt on motor pulley. Groove side faces the pulley.
Gently release tension on the idler so it rides on the left side, back (smooth) side of the belt.
Thnx so much finally have it put together 
Glad you got it back together.
For future references I started to put together a gallery of dryer belt and pulley idler images here.
