I tried writing transparent under

#container .box {

background-color: #ffffff;

width: 250px;

margin: 0 10px 10px 0;

float: left;

overflow: hidden;

line-height:9px;

}

where it says "background-color"

and that seems to work to make the transparent images, transparent on my blog.

But, then It also makes the writing posts transparent too, and the words are hardly visible with the background I have.

So my question is how can I make just the images transparent, not the writing posts too.
