I know there was a thread some months ago that listed which girls are used for the page graphics. Couldn't find it today. Does anybody know who's the girl in the Software-Info Panel on the left?

If you mean the middle girl in the pic above "Upcoming Novelties for VirtuaGirl", I'm not entirely sure, but I think it might be Lucy Love from VG2 (so a possible VG Classic release I would assume)

This picture is Morgane from her 'Double Agent' card A0568, the inset on the left hand side of the software screen is also her, with a closeup of Jewel from her 'Dancing Flame' card A0405.

Found her at last (thanks to colaborateur on another thread)

If this is the girl you were looking for, it looks like she might be one of this Friday's 4 new releases, or perhaps the first monthly bonus card for VIPs.

If you mean the girl of the left hand side of the VG Regular skin (I didn't think of that because I use CVs Aria Giovanni skin), then it's definitely Jewel, with a smaller pic of Morgane below
