i was trying to have an image on the back of my thumbs, on roll over, but a border from the bground appears.


andrew_ohlmann suggested to add

background-repeat: no-repeat;
background-position: 10px 10px;

to my css after adding


#cardthumb_123 {background-image:url(url_of_image_here.png);}


but couldnt get rid of the border...

any help will be apreciatted!

thanks
