Images messed up in post

Hi.

First of all. Thank you for this great theme.

I hope you or any other can help me with this. I’m using version 1.3.1 of sampression lite. But suddently the images in my post do not align correct. I think it has something to do with the styling, but i do not know enough about css to correct this.

You can see, what i am talking about her:

The images should be placed on the lines.

Thank you!
