I don't understand why you built a site for someone else who states they are "web and graphics specialists"! Couldn't they do it?
SEs don't care about images. Only when they prevent loading and stop a spider are they a problem. However there are such things as Alt attributes you need for all graphics to both make your site compliant and help
SEO (and Document declaration at the start of your code). SE-wise you need a much more keyword orienatated text - a bit ironic in a site that declares "We are experts in search engine optimization activities."
It also would have been nice to see a designer's site built without tables.
Personally I don't like the animated gif and don't see the point of the genie graphic. Generally the graphic style is a little heavy and not very original.
