I want to align K2 images to the left of the page, by default they are centered.  I'd like to make images about 300px in width and for the text to wrap around (the way they do in Joomla articles)...

I've modifited k2.css -> div.itemImageBlock, removing the margin center, specifying "float left", I have also changed the div class itemImage to float left ... It seems to ignore my css code ...

Can anyone tell me an easy way to do this?

Maybe I'm stating the obvious but did you empty your k2 cash then refresh your browser?

Yes

Plz include a link to the site if  its live for firebug
