The pagination problem seems to be related to the Yoast Google Analytics plugin. This is discussed here http://www.datafeedr.com/forums/showthread.php?t=8783

Regarding the tags page, that's because your tag page is displaying thumbnails, not images.
Go here: The Factory > Your Store > VIEWS > PRODUCTS BY TAG > Default > Product list and change [product.thumbnail to [product.image
