[SOLVED] Remove whitespace between images because of new line in code

Hi all,

I am using the twitter followers plugin on my website, which is showing the icons of some of my followers in the sidebar. There is a small whitespace between all the images, which I don't want, I want all the images to stick to eachother.

Of course I tried some things (used css display option), nothing works. I also think I know why it probably shows these spaces. It's because between all the <a href></a> blocks, the code goes to the next line, which creates a white space by the browser. But can;t solve this, cause it's because of a FOR loop in the PHP code.

How can I solve this?
On the plugins page there is a screenshot with no spaces, but nobody helps there...

Hope you guys can!
