First, open Screensnapr's settings. Enter the following in the "Server" tab:
(x)use my own server for hosting.
Host: MePic.tk
Username: a6515520
Password: dream1
Upload directory: /public_html/S/
Output URL: http://MePic.tk/?img=S
For the 2 last drop-down menus, you can enter whatever you want. To keep the links short, I entered "5" and "none".
Thank you!!
