Since the forums don't let you upload pictures directly, I thought I'd share a handy trick for getting pictures on the site using your dropbox folder.
1. Upload your picture to dropbox
2. Create a dropbox link (usually you right click and select "copy dropbox link"
Dropbox makes a link that allows someone to download the file, you need to edit the URL so that it is setup to display the file, you do that by manually editing the url
change the text at the end of the URL from ‘?dl=0’ to ‘?raw=1’
For example:
This: https://www.dropbox.com/s/5bs4a7c2gs38wm0.png?dl=0
Becomes: https://www.dropbox.com/s/5bs4a7c2gs38wm0.png?raw=1
Paste the new link between between the HTML image tags" as follows "[img]Link[/img]" (the button that says IMG in the post new topic window).
