After I built my new computer, I went to put a photo gallery together and realized my Photo Gallery app ran at about the same speed as it did on my old PC. I was running all the thumbnailing and image scaling in a single thread, so it was only taking advantage of one core (and I have a simulated EIGHT in my new PC) no matter what. So I fixed it.
Photo Gallery Maker 1.2 has support for multi-core systems. It will run ([number of simulated cores] / 2 + 1) threads for thumbnailing and image scaling. Just about every system available today should see a noted improvement from version 1.1.
There was also some funny stretching going on with the thumbnails on the generated web page. I fixed that too.
