I believe the spinning effect has to be done using JS, not CSS.

With regards to the sizes, changing the size of the circle can be done by changing the "height" and "width" properties in the CSS.

For now, you images are going to need to be squares to avoid skewing. I tried looking into an alternative but it didn't work out. - Try adding the following property to the CSS. It won't work for Internet Explorer but it seems most people don't care about that. Also, I am not convinced using the overflow property is necessary. However, it doesn't seem to hurt if you keep it.
