After much trial and several tribulations here is a background picture. Ann informed me she was tired of autumn leaves and it was Christmas. Why is she always the instigator of everything? Anyway I more or less figured it out. First, convert to "blogger in draft" a sort of beta form of blogger. Which I did in case you notice the format is a tad different. Go to Design.>templatedesigner>background image>upload image.
The image is supposed to be no larger than 1800 x 1600 pixels but I had to get this one down to 500x333.
It's a bit much but the only other choice is to put the picture in the upper left or upper right corner and then have a plain yet-to-be-determined color for the rest of the blog. Feel free to vote. Or find a better Christmas picture. At least it's better than solid black. We'll do better as we figure this out. L, D.
