Oops, missed this thread til now, sorry...
Cheers for the photo - as has been said, it looks like a setup issue. The chain line won't be causing the skipping so don't worry about that.
Try taking a link or two out and that should solve it, try and get the chain more like this: http://tartybikes.co.uk/images/bikes24/large_inspiredteam1.jpg
If you still have issues there is one final thing you can do and that will 100% sort it, although it does require a quick modification to your tensioner.
Let us know how you get on
