I am looking for a program that can resize a whole lot of pictures at once. Cause to put photos into the gallery on my website, I need to size them down but that is a real pain, when you have 100 pics. So I need a program that can resize and renaming would be a plus, a bunch of photos. Any other batch capabilities would be helpful to. Thanks. And of course im only looking for freeware.

You can do that using PHP.
On upload you can scale that up or down accordingly.
