They look blurred on my computer. You should save your pictures as .png files instead of .jpg files. The file size will be the same but quality will be improved drastically.
Actually, they are .png files already but somehow Pagesgoogle transforms them into jpegs... However, if they're hosted, they won't blur so I'll try that today.
Oh very, very nice indeed I must say (and who's been a little cheeky taking the BBC's election maps from Wales and Scotland in 2007 eh?). I notice that you have decided London into a North London and a South London is there a reason for that?
Those maps are there while I'm making maps myself. That must be the Thames River dividing London, thanks for noticing that. I'll try to fix it.
