I'm looking to update the masthead a bit...

So, it's been over three years since I started this blog, and I reckon that it's now time for a minor facelift.

I'll be doing this in small increments, since I'm generally very happy with the layout and look of the Blant. One of the things I want to do, is add an image of the London skyline, or something similar, like a panoramic photo of London, to use in the masthead.

The problem is in either finding royalty-free imagery, or free stock photos, for this purpose. Failing that, the problem is in finding a suitable vantage point from which to take my own panoramic photo of London.

So, here's the question. Do you know of a decent vantage point, or free-to-use-and-abuse imagery that I can use?

Any ideas?
