make a message popup verifying avatar size

[kh99]

Maybe something like this: edit the modifyavatar template, find this (near the end)

<input type="submit" class="button" value="$vbphrase[save_changes]" accesskey="s" />
<input type="reset" class="button" value="$vbphrase[reset_fields]" accesskey="r" />

and replace with this:

	<input type="submit" class="button" value="$vbphrase[save_changes]" accesskey="s" onclick="return show_reminder(this.form.avatarid)"/>
<script type="text/javascript">
function show_reminder(avataridObj)
{
    if (!($permissions[avatarmaxwidth] || $permissions[avatarmaxheight]))
        return true;
     var value = -1;
     for (var i=0; i<avataridObj.length; i++) {
        if (avataridObj[i].checked) {
            value = avataridObj[i].value;
            break ;
       }
    }
    if (value == 0)
    {
        return confirm("Are you sure the image is within the size limits ($permissions[avatarmaxwidth] x $permissions[avatarmaxheight])?");
    }
    return true;
}
</script>
		<input type="reset" class="button" value="$vbphrase[reset_fields]" accesskey="r" />

(You could put the js function in the script tag that's already at the top of the template, but this way I only had to describe one replacement).
