Hi,
Currenty I m using a 1x1px transparent gif for my css sprites, but I m not sure if this is a good way to do that. I use code like that:

img.home {
width:46px;
height:44px;
background:url(img_navsprites.gif) 0 0;
}
I now wonder if its ok, to put such images into a link, as it would be seen by search engines as just a 1x1px image. I read somewhere that the may not follow such links.
Can anyone tell me, if that is a valid practice or whats the best practice to use linked css sprites.
thanks
