I had a personnel message asking for help with picture posting, so thought I would post some pictures as I could not do it in the personnel message.
I do not use my phone, I mostly use a digital camera and it is actually set at a pretty high resolution-3M
1) i take my pictures and save them to my computer hard drive
2) When I do my post I click on the "add Picture" tool

3) Select "from computer"

4) Select "Browse" and locate your picture on your computer and select it. The file should show up in the Files selected box

5)Then select "Upload File". This some times takes time, so I try not to do more than 3 at a time

6) This is how it should look in your post while writing it. If you select "Preview Post" bottom right hand screen corner-you can preview and see how your picture will turn out in the post.
