Internet Explorer image bug

Hey there,

I’m facing serious problems showing images on my website. With Chrome and Firefox, the pictures show as intended. But if I use Internet Explorer 10, the images somehow keep on getting smaller and smaller until you can barely see them anymore:

Any thoughts on that?
Thank you very much!
