Center Embedded Image in Table Row

Hi guys,

I'm facing a small issue here.

Currently an example row of my table looks like this:

What I now would like to do is centering the language and filetype icons. I've tried several css commands so far but (probably because i'm not that experienced with CSS yet) it didnt work.

If anyone of you could help me, I'd be very happy :) Thanks a lot! If you need further explanations, just let me know.

(by the way, i'm really impressed how helpful this forum is so far - keep up the good work! ;) )

anyone got an idea?
