Try doing an Image Search in Yahoo or Google. Just type in the kind of cake you're looking for. I.E. baby shower cakes...or be more specific and type in baby rattle cakes, baby bib cakes, baby blocks cakes, rubber ducky cakes, etc...
When the screen opens up there should be a bunch of small pictures of cakes. When you click on a picture the screen will open up as a split-screen with the photo on top and the bakers website below. If you click on the picture it will enlarge the it, by clicking on the website below you can view all their other cake pictures too and many of these websites also have links to other cake websites so you can just go on and on sometimes! Try it!
I automatically save pictures of cakes I really like or could use (that is know I can duplicate or use parts of it for inspiration). I have a huge file called Cake Ideas and have it sorted by type of cakes: Floral, Wedding, Kids, Baby shower, Masculine, etc...I also have a file for Interesting borders and Pretty Writing.
Try it! And Good luck hunting!!
