How to make a picture "pale" for Tumblr?

[Shirley]

You can see the HTML that she used by opening her tumblr page and then clicking "source" or "page source" in the view menu (depending on what browser you're using).

She used CSS styles to produce the effect:

.photo img{
align:center;
border:5px solid #866057;
margin-bottom:6px;
filter:alpha(opacity=60);
-moz-opacity:0.6;
-khtml-opacity: 0.6;
opacity: 0.6;}
.photo:hover img{
border-color:#997a6e;
filter:alpha(opacity=100);
-moz-opacity:1.0;
-khtml-opacity: 1.0;
opacity: 1.0;}
.photo a:hover img{
border-color:#997a6e;
filter:alpha(opacity=100);
-moz-opacity:1.0;
-khtml-opacity: 1.0;
opacity: 1.0;}
