Images compressed in slideshow

Hi,

First of all, congrats to the author of this great theme. I’m building my portfolio based in SoloFolio, but I’ve just one question about it. When I see my pictures in a slideshow, when it changes from one picture to the other it seems like the first image is compressed before it changes (it’s just one moment) and when the new image apears it is suddenly expanded. It’s not a very important problem, but I would want to learn if it is possible to avoid it.

Thanking you in advanced!
