Ok, I finally figured out how to upload pics into your posts. This is how it is done, pay close attention
Step 1. Find the picture you would like to upload (this is easier if found off the internet)
Step 2. Copy the link
Step 3. When posting the pic, you will notice all the nice little icons ABOVE the post box (where you're typing). The THIRD to LAST one on the FIRST row, has an icon of a picture.
Step 4. Click on that picture!
Step 5. Paste the URL into that box, and press "ok"
You're pic should be uploaded then
For an example:
