It's easily done as East Gill Force is marked but not named on the 1:25000 OS map. I recall someone making the same mistake in an issue of "Best of Friends" once, but that is easily capped by a picture of Barmouth Beach in "BoF" entitled "The English Summer". Barmouth is in Wales ...
I would avoid percentages as the layout becomes fluid and text columns which read best with approx 8-10 words a line, will expand to many more words a line on high res screens. They then become more difficult to read because your eye finds it difficult to scan to start of next line.
Hi, very elegant website with great photos. The thumbnails can be enlarged a bit and compressed to 20K or less (using save for web in photoshop). I think one small thumbnail I saw was 100K.
Just one comment, my laptop is running 1280 x 800 (widescreen), and there is a lot of whitespace between the header (and menu) and the page numbering. It causes the image to be half visible. I would delete at least two of the paragraph markups.
percepts makes some good comments, and I won't add to them.
