Sharing and Like-Function within Portfolio

[NilsDotArt]

The image gallery/portfolio tool already gives us a lot of options. It is really well thought out. One crucial feature is however missing - a social sharing button along with each image.
As an artist, I want my website visitors to be able to share my work via their social media channels as easily as possible since this makes for great free marketing. Wix actually does a great job with that specific feature. They also have a "heart"/favorite button, which makes a portfolio more engaging.

Eventually, it would be ideal to also have a commenting option along with every image within a portfolio, but for now "just" a sharing option would be great.
