Removed Float Attributes in Theme but image still aligns left instead of right

I have a WP theme where all the images can be aligned to the center or to the left
If I try to align it to the right it simply ignores it and aligns it to the left. Here is an example: http://best-offers-online.com/

I removed the float attributes, tried to change them, nothing works.
What can add to my CSS so that it will simply accept the alignment that I specify?

Thank you

 

Any ideas will be greatly appreciated
