[Theme Scrappy] Images at different sizes

I’m using Caroline Moore’s Scrappy theme and if you take a look at my sidebar at http://chicklitreviewsandnews.com you’ll see under the “Recent Reviews” that all my images are different sizes. I don’t know why because they’re all set to be width=”102″ height=”150″.

Can anyone tell me what it is that’s causing my images to be different sizes even though I’ve specifically told them what size to be?
