Display in columms

Hi,
I would like to display the list in form of a 3 column without the titels and larger images.

Currently I’m using this code – I did edit the column bit to the style ccs. but it doesn’t seem to work

[display-posts tag=”london” image_size=”thumbnail” posts_per_page=”-1″ order=”ASC” orderby=”title” display-posts columns=”2″]

Any ideas?

Thanks
Tina
