You are right ArtsCad is a bit slow but while art.com is unavailable, it could be a good alternative.

I only pay QR100 annually for a 100MB website with a monthly bandwidth of 2 GB. There is no need to advertise. You can submit your site to different search engines to be more accessible to surfers.

Given the amount of traffic in your original gallery, you have indeed lost a lot. I hope you could somehow restore things back. Good luck.
