Thank you for your reply.
Your iFrame suggestion works perfectly well for my purposes. My gallery will now have the exact look and functionality I was looking for. Great. I just had to place the iFrame specifications within the target div and now everything is fine. The rest is just a question of tweaking details here and there, but that's all to be done on my side.
Great to have you at the helm over there. You're doing a great job.
Many thanks for your attention.
