I believe the PnP site has a file size limit. When I try to upload pics that are larger (1 MB or more) it acts like it loads but does not show up. When I resize the pictures and make them 100 KB or less, they show up.
The steps are:
1) Click on the "Upload Attachment" tab underneath the "Post a Reply" text box.
2) Click "Browse" button and find the picture on your computer that you want to upload.
3) Click "Add the File" button.
4) If the file uploads successfully, you will see a box to add a file comment and below that, two buttons - "Place Inline" or "Delete File". To attach the picture, click "Place Inline"
5) You can then preview the post by clicking the "Preview" button or go ahead and submit the post by clicking the "Submit" button.
