If you have some web space you can just use the [ img ]http url to .jpg pic[ /img ] without the spaces in the  tags.
Best to keep pics at 640 pixels wide or less.
Full suspension bikes aren't hard, just use a jackshaft and completely eliminate the second chain.
As for tires, Kenda's are good.
I could be biased though, my wife of 25 years is named Kenda ;-}
