A place where Ancient Ancient armies can peacefully retire to...
Hmmm, I should leave it for a week or so. Blogger does weird things now and again (it wouldn't let me post pictures for a couple on months once). Fingers crossed.
Try taking off your header picture. Some time ago I got a message saying that I had no more space left for photos on the blogs and would I like to buy more space, which was scary. But once I got rid of the header I was OK.
Haven't had any messages like that. What I have just tried is deleting a number of posts that are, shall we say, of lesser long term importance. See if that has any effect.
Oh, I'm also trying to reduce pictures by 60% as I redo them, again see if it works!
