Recently, I was invited by Google to be a test user of Google Open Gallery. (Along with probably a million other people!) Google has taken its
Cultural Institute platform, which it's been using to present high-resolution images of museum collections, and tweaked it for individual artists to use. I decided to upload the fifty images of my "Fifty Paintings" Kickstarter project. Here is a link to my site:
https://pleinairpainting.culturalspot.org/
I found the interface extremely easy to use, and although the system permits uploading images that are up to 50 megabytes big, I chose to upload much smaller ones. I don't know anything about the download capabilities of the system - that is, can a Chinese sweatshop download my high-resolution images and then set about mass-producing paintings based on them? - but it would bear investigating if you are concerned about copyright. I've had a few people look at my site, and they seem to find it a pleasure to use. You can also really zoom in on the images to see the fine brushwork.
If you would, please take a look. I'm eager to hear your thoughts. Here's that link
