Thanks Jason- In my case the application needs to show all 12 images at the same size. I could switch to a listview but that will degrade the user experience.
I have also been thinking about switching to a webview that loads a static HTML page containing all 12 thumbnails. Seems silly, but if I can't beat my memory issues the I'll use it as a last resort. I checked out the thumbnails, they're already sized to 100x100 jpgs of roughly 4k in size, seems like I should be able to hold them in memory 4x12 = 48k, so there must be something else going on.
