I'm maintaining a Facebook iFrame application, and my client is worried about the transition to Timeline. Basically, they want their home page to have a big icon next to 'Photos' that takes the user to the page hosting the iFrame. The tricky thing is that users can "pledge" within the app, and they want the link icon to look different depending on whether or not the user has pledged within the app. Is there any way to do this?
Assuming the answer is no, is there a way to add a second icon for the iFrame app so that I can customize one to look different? Or would I need to set up another page hosting the same iFrame?
Thanks!
