Yep- That was it. I just made my thumbnails the same px horizontally and vertically.
Now I have another issue with the grid. If you can't help me here I'll start another thread... But:
When I choose (in NSP) to show "K2 Articles" and I choose my 1 article (241) I get an error on that grid square.
Seems it will only display by category. Sure I can choose by date and organize them by date, but it would be a bit tedious. I have to arrange my grid in a certain order.
Thoughts?
