Fixed 3 bugs, 1 of which was causing error in scrolling

There were 3 bugs: link2 = [] was placed in withing while cycle, thus resetting links2 (all links gathered) every time during scrolling of user's wall - that caused impossiblity to scroll bellow 45 posts.

The url for post was saved from link, but link was never defined. This also caused problem for saving preview_img

Lastly, preview_img was being set outside of try zone, which could cause it being set despite success of try code.
