[Plugin: NextGEN Gallery] Sidebar linking problem, Gallery linking problem

https://visualthumbprint.com/portfolio
1. You’ll notice the first gallery doesn’t hyperlink unless you roll on the outside of the image. How do I fix?
2. On the entire gallery – including the sidebar – only when you roll over the outer border of the photo can you actually click to link – how do I make it so that the entire image area / thumbnail is a link instead of just the border?
3. On the sidebar, only the bottom row (and occasionally one of the middle ones) will actually link – the top row doesn’t link at all. How do I fix?
Thanks so much for all the help!!! I feel like I’m going crazy trying to fix this!
