How to post a picture:
1- Write your post.
2 - Click on the button "Attachments"

3 - Make sure the image is a jpg or png
4 - Make sure the image is smaller than 1Mb - 1024 pixels long side is good.
5 - Click on the button "Add Files..."

6 - Choose your image (cellular, tablet or computer) and WAIT for it to upload.
7 - IMPORTANT - After a few seconds 3 new buttons appear below the image thumbnail: Click on "INSERT".

READY! Your image appears to everyone as seen below:

Important to note: If the posting goes wrong because say a checkbox was not ticked or a category not choosen, it may look like the images are still there. However, they will not be. So you will need to upload them again.

That's why using the "Preview" button is so important *before* hitting "Submit" after a failed first try.
