Stencil (free images) and posting to Social Media
I have struggled when it comes to social media - heck, I cannot get Instagram to work for me so that is saying something. Will update Instagram on another post and at later day :)
My post is about Stencil.
Stencil is very easy to learn and can even post (send) your pictures to Facebook, Pinterest, Instagram, Tumblr and a couple of others (from memory).
This platform has free photos (10 per month) and a paid version. When starting out, they provide a bonus, of up to 15 free photos for the 1st month.
So, if you are struggling for any photos, try giving Stencil a go!
