Edit Imageset update_image() incorrect assignment

in includes/acp/acp_styles.php;

'A_NAME' => addslashes($imageset_name)
should be;
'A_NAME' => $imageset_path
as
$imageset_name might not be the same as $imageset_path, e.g.

DB subSilver 3 != db_subsilver_3

BTW: I'm getting old, I thought I had reported this...
