I’ve also found that there are many Tumblr art blogs that have options for you to either submit your art or upload your art and artist news, announcements or articles along with art images. Add your own art or cross-promote with another artist to mutually share–this is such an easy way to get more exposure. Also, many Tumblr art blogs also have Pinterest pin buttons. Once you add you artist article and image you can pin it to Pinterest.
Here are just a few Tumblr art blogs that accept your contributions of images and writing–there are many more:
No Ones Nemesis http://noonesnemesis.tumblr.com/submit
A Thousand Words http://a-thousand-words.tumblr.com/submit
Fuck Yeah Expressionism http://fuckyeahexpressionism.tumblr.com/submit
On the Art Finder site http://www.artfinder.com/about you can build your own art profile, add the link to your website, and connect with art lovers and collectors. An easy way to create a strategic online presence amid art lovers.
I have found that art galleries internationally promote their art publications on the Issuu site, where you can create a free member profile and join one of the groups such as the Art People group that allows members to upload an ebook up to 500 pages. Do you have a digital manuscript of your own artwork? This is a great place to share your own art ebook!
