The signature does fit into the sig area without the scroll bars, its 500x196 which is smaller than the max non scroll sized sig (509x222). The only reason its scrolling is because you have two sigs.
I can make it narrower but not longer, it'll end up being too long and having to scroll. As far as height goes it'll only shrink if i make the eGO logo smaller than it is now. Its up to you, let me know what size you had in mind (i.e. 500x150)
The image of the pickle is just one of a larger picture of multiple pickles. I removed a single one, cut it out, modified the edge, duplicated that one pickle, rotated them, shaped using perspective, added a gradient shader, beveled, fake self-shadowed then added reflection to it.
Basically theres alot you can do w/ one image.
