Need some help with ideas

I'm trying to figure out what to do for the centerpieces for our wedding.  We both would really like to incorporate photos into our centerpieces and DO NOT want flowers in the centerpieces.  We were thinking of doing the photo cubes with pictures of us through the years, but they are only 2" by 3" and I'm not convinced now that they will be big enough.  To be honest we will probably have about 30 tables but we don't want to pay an arm and a leg on centerpieces.

If you have any ideas PLEASE let me know. 

Oh and by the way I have been busy planning for the wedding lately, and got terribly sick this past weekend (fever of 103 Saturday, 102 Sunday and finally back to normal today).  I also have a terribly annoying cough that seems to think it is important to stick around.  I disagree but we are fighting. 

Anyway on a happier note, on Friday we heard that there is a 90% chance we will be having our wedding at Grace Church in McKean.  We meet with our photographer this Sunday and we get to meet with the wedding coordinator from Grace Dec. 5th.  Things are starting to come along.  We are nearly certain we have our guest list finalized also (although my mom hasn't had input yet, so that may change but I'm hoping not as we are very near 350 people.)  We picked out our colors of Sage and Grape (that's what the bridesmaid dresses are called).  And I got photoshop for my birthday HOORAY! So I get to work on designing our invitations! HOORAY!  I've always enjoyed trying to design things and I feel like it will be very special if I do get to design our invites.  Thanks again everyone!
