Actually, setting up a gallery or flickr account might not be ab ad idea for her business. You can link them all to the website. You can do the free one for 100MB a month, or you can do an annual fee (I do this) for unlimited @$24.95 a year.
Im not sure how your website is setup, soi dont know if settign up a gallery is an option for you, but there are lots of gallery freebies out there (ZenPhoto is one)
two little thing i might HIGHLY suggest.. Please get rid of the red background on the front page.. its harsh on the eyes.. detracts from teh picture of her lovely cakes. Neutral Colors are a good thing for backgrounds.
Stick to one theme. Dont change colors on each page, its fun to change it up a little bit.. but comformity will keep a customer on your site longer, as it seems like a more professional business.
If my (or anyone elses) critiques bother you, i wont say another word, but those are some issues that will help you out a lot.
it looks MUCH better than it did last night
I disagree about the "Yellow" cake. if you dont know what Yellow cake taste like.. well.. there is no other way to describe it.. its just.. yellow cake. Even Betty Crocker calls it Yellow Cake.
Also.. if you are able to see/edit the code any, edit this on each page (if its a wwisyig editor, see if it has somewhere for you to edit the Title of the page.
