css image filters

[jhappeal]

I am trying to apply Filter: Gray to a background image

For example:

a.someclass {
background-image: url('images/someimage.gif');
background-repeat: no-repeat;
background-position: center left;
filter: gray;
}

I do not think this is possible but maybe someone smarter than I knows a work around to make this happen.

The filter property only works in IE, but it won't validate. CSS isn't your solution to this, but the PHP GD library does have something like this if I'm not mistaken.

You would be safer all round if you applied the filter effect in a graphics package and then used the resultant image.
