Hello sheila and welcome to the forum. I have painter X as well as Painter Essentials 4 so I am a member of the Painter Factory Forum for work done in Painter X and this forum for work done in Painter Essentials 4.
I understand what you mean about it saving sanity as I try to use it whenever I feel a bit stressed or troubled.
To upload pictures go to 'show your creations' and click to write a new post.
You will see some tabs at the top of the page that opens
The 'compose' tab lets you write about what you want to say
Click the 'options' tab.
This allows you to browse to where you picture is on your computer (your picture needs to be less that 256 k) click save and once it is safely uploaded click on the post button at the bottom
Hope this helps
