[shadowbox]Facebook Timeline for Pages was introduced in March 2012 which got rid of Fan Page photos as described in this post. [/shadowbox]
Your Facebook account has undergone numerous changes in the last few months including Fan Page photos and the way we display images on our profiles. The current layout allows you to have 5 images on the top of the page. On your profile, you can use a social media app like Profile Maker to upload an image and make gorgeous collages that resemble peek-a-boo image masks. There's no such luck for generating lovely Fan Pages with this technique, and I'm not sure why but it might be a decision made by Facebook based on “security issues”. 🙂
Quick Tip: If you have more than 25 likes on your Facebook Page, you can claim your branded url here.
Contrary to the behavior of photos on your profile, Facebook Fan Page photos rotate in unpredictably random sequences that leave little room for snazzy collages or any other artistically graphic design treatments. So there's no need to pull out your snazzy, hi-tech Canon DSLR to take a professional photographs just for to get the job done.

Fan Page Photos Secrets?
They call it a secret, not me, but this is what you can do. Create thumbnails with what I like to call “mini-ads” on them to focus the attention of your fans on the products or services you're offering. Don't waste that valuable Fan Page real estate with pretty pictures – try uploading a few simple banner ads instead. In this video, I demonstrate how I used Google Docs and Awesome Screenshot to generate the perfect size image to upload on your Fan Page.
Make use of Fan Page photos to let your fans know that you're open for business, showcase your best selling products, create calls to action – do whatever you can within the size limit of 97 x 68 pixels. Take a look at how Get 10,000 Fans uses the Fan Page photos and tell me what you think about using them on your page. 
I attended a free training session from Get 10,000 fans but I haven't purchased anything from them, so it wouldn't be fair for me to endorse their products. However, I do like the creative use of the “mini-ads” displayed on their Fan Page photos in this example, it really grabs your attention.
