Thanks.

Well for a start you've got a naked pair with {1,5} on the top row (cells 5 and 8). Bearing this in mind, you know exactly where to place a 9 and then a 6 (in the top row). Then you can place a 9 in box 3, and so on...

Oh yeah, and because of the {1,2} pair in box 7 (bottom left) you can make some exclusions in column 1.

There's a few ways in, really. My advice (which I tend to give to all newbies) is to read some of:
