Google Draw may not be the most sophisticated or feature-rich drawing program out there - but it takes no time to get started, it is more powerful than it looks at first and, importantly, it integrates perfectly with all the other Google tools.
If you want to insert a sketch into a document, this is the easiest way to do it.
And it's free, of course.

Pinterest functions as a social media site but its focus is very much on pictures and visual imagery.
Think of it like an online pinboard - or, in fact, an unlimited number of pinboards.

It's a huge site and therefore a great resource.
Google Arts and Culture is a hugely ambitious project which is gradually collecting high-res images of many of the world's greatest artworks.
It includes virtual walk-arounds of some of the most famous galleries in the world.

An amazing resource
