Topic: Avatar changing image size

I've a problem! I want the $matches[1]to change the image size to  <!--fonto:Impact--><span style="font-family:Impact"><!--/fonto-->height:100px;<!--fontc--></span><!--/fontc--> and <!--fonto:Impact--><span style="font-family:Impact"><!--/fonto-->width: 200px;<!--fontc--></span><!--/fontc--> instead of just writing <!--fonto:Impact--><span style="font-family:Impact"><!--/fonto-->[img]THE_LINK.png[/img]</span><!--/fontc-->

Use instead of {avatar}: [img]$matches[1][/img]

$matches[1]

.post-avatar {
width:200px;
height:100px;
}

Re: Avatar changing image size

Where's the css file?
Also specifying the size of the image in the form to post a news, PageSpeed told me to specify the size.
