There is no way I would tell you to go jump in the lake. I will consider some of your suggestions later, but first, I want to discuss the image.
I'm not good with images and had the banner created for me. I'm not sure what you mean by making it 1000 and then cropping and telling it to be 1250. I know how to resize it using Gimp or IrfanView, but what you are suggesting escapes me. If you can explain in more detail, I will be happy to try it and see how it looks.
More later, but let's deal with the image first.
