I recently talked about posting quotes from famous artists to your social media pages. You can take this one step further by adding the quote to a custom image! Images get more attention than just text in most cases.
You can use your own image like I did here or use a solid colored background. One thing to notice is that I included my website and facebook URL (This was the one I posted to facebook, I had a different one for each platform). This post is more likely to get shared by lots of people than just the image of the tiger painting alone, which in turn gets my website and facebook URLs seen by tons of people!
