the problem with a skin in iGO-Primo is the resolution, the corresponding width for landscape and portrait in mirror.ini.
I got around that by unpacking a skin and embedding it in a branding.zip.
In ->[Only registered and activated users can see links. ], ->[Only registered and activated users can see links. ] is included as a branding, that fits normally, as the already known resolution folder is used here.

just test it once
