Ok i'm tryin to do somethin and i'm pretty new to those things so i'm gonna try to be clear :
Actually i have a (left) sidebar, and there is a category list. So you can click on one of the listed categories and the post appears (at the right)… no surprise ok.
Now what i would like is when you click on one categories you have a list of thumbnails that appear at the right (where the posts appeared previsouly). Then you click on one of the thumbs - each one representing one post - and then 'bang' you have your post.
I have no idea how to achieve this, i don't even know if its possible so some help would be much appreciated, thanks.
