I think I found an awesome way to put up grids of photos- Picasa! Guys, blogger is the WORST for trying to format pictures. The. Worst. So I went a-looking online to see if people had found any workarounds, other than our default of creating a grid in Photoshop. And Picasa scores big. I did this collage in like two seconds. 
Love love love.
(Please don’t judge that I take disgustingly cutesy pictures with my kittens. I’ve just discovered Mac’s Photobooth program, and my husband doesn’t want to sit still for pictures. These are my only semi-willing victims.)
