i tryed the blog out early it add the text for the blog but wont show image on the blog
has anyone else had this problem please advise thankyou

Well, theme-wise, that's far from default v. 2.1.0.2, but actually, the limit is only
the VISUAL Space, the actual 'Frame', likely defined by CSS, where Categories
usually are placed in, to display. And this limit may cause invisible or misplaced
Category Links, depending on, how they have been coded. (max-width/max-height)
Just an idea...
