Alright sooooo design a header that is 745 pixels wide and post it or email it to me or something and if it's good it will go up.
There's only so much you can do with the rest of the blog as far as aesthetics go. Although if you have a good idea for that or can create your own html or something then you are officially the new layout master cause I don't have the slightest clue how to do that lol.
Also, everyone needs to go into their settings and change their posting to the updated new style. It will allow for uniformly larger photos.
