Where is a good place to make a photo montage these days?

When #1 was a baby, I used Onetruemedia.com.  Is there something else people use now?  I have a mac, so I could use iphoto, but I'm wondering if there is something online.  #2 will turn one soon and I feel like I should do something for him, since we probably won't have a party.

 Thanks
