Display image on a gradient background on hover via css - html

Question

I have this background:
.background:hover {
background: #F4F4F4 url(../images/arrow_down_over.gif) no-repeat right;
}
that I would like to change into a gradient like this one :
.background:hover{
background: -moz-linear-gradient(top, #f4f4f4 0%, #eeeeee 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#f4f4f4), color-stop(100%,#eeeeee)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #f4f4f4 0%,#eeeeee 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #f4f4f4 0%,#eeeeee 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, #f4f4f4 0%,#eeeeee 100%); /* IE10+ */
background: linear-gradient(to bottom, #f4f4f4 0%,#eeeeee 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#f4f4f4', endColorstr='#eeeeee',GradientType=0 );
} /* IE6-9 */
But I would like to keep the arrow image. I can't find a way to do it. I did try something like this:
background: -moz-linear-gradient(top, #f4f4f4 0%, #eeeeee 100%) url(../images/arrow_down_over.gif) no-repeat right; /* FF3.6+ */
or add this after the gradient properties but without any success.
background: url(../images/arrow_down_over.gif) no-repeat right;
I can't add another class so I have to deal with this CSS. Any idea how to do it?

You may try:
background: url(../images/arrow_down_over.gif), linear-gradient(...);
Multiple backgrounds must be comma-separated rather than space-separated, and they weirdly stack from top to bottom.
Also note that this is not necessarily supported by all browsers.
