Hello
I have been researching art gallery software like masterpiecemanager.com, myonlinegallery.com, gallerysoft.com, gallerysystems.com for integration into my wordpress site whether it's a part of wordpress or stand alone with a link from my wordpress site. I wondered if I could get feedback about these and if y'all could suggest something else like an etsy plugin that would be more beneficial. There is no wordpress plugin for these other than etsy plugins which don't do everything I want. If y'all can develop a plugin similar to these art gallery software sites, I am sure it would be a huge hit.
Thanks
Andrew
