OK, i found it my self :-)
IN the file config.rsgallery2.php i did this:
On line: 341 i replaced this:
$thumb_html = "<img $imgatt src=\"".$mosConfig_live_site."/components/com_rsgallery2/images/no_pics.gif\" alt=\"No pictures in gallery\" border=\"1\" />";
With this:
$thumb_html = "<img $imgatt src=\"".$mosConfig_live_site."/components/com_rsgallery2/images/no_pics.gif\" alt=\"No pictures in gallery\" border=\"1\" hspace=\"5\" vspace=\"5\" />";
And on line 357 i replaced this:
$thumb_html = "<img $imgatt src=\"".imgUtils::getImgThumb($thumb_name)."\" alt=\"\" border=\"0\" />";
Whith this:
$thumb_html = "<img $imgatt src=\"".imgUtils::getImgThumb($thumb_name)."\" alt=\"\" border=\"0\" hspace=\"5\" vspace=\"5\" />";
hspace and vspace can be replaced with other numbers for wider space
