This is the image I chose early in the week. I also offered to pay extra for the trouble.
That may be the case but from reading what you and Jeff posted above it appears he let you know there was an issue with that image and you then chose another to go with, right?
So if that's the case and you chose another and okayed it and he told you he would be making it that night and then you come to the forum and email or whatever and try to change it yet again even after he said he was already going to be making it there is no reasonable way to hold him responsible after you already approved the image.
Not to mention if I were Jeff I would tell people to make sure they chose an image they wanted before even ordering and once the order was placed there would be no changing it. But Jeff is already nice enough to let people make these changes along the way which is obviously taking up more of his time and causing him more work in the long run.
So, sorry to say it but, I don't see how anyone could reasonably think that he should shoulder the cost of redoing something that you have had a month(not including time spent thinking about it before placing the order) to make up your mind on.
