Salam sister,
I'll show you how to do it easily...I do this (I host my own pictures).
1. Go to
http://OurIslamic.com
2. Register an account (it's really fast, takes less than a minute)
3. Go to the forum
4. Go to the "images and videos" section
5. Make a new thread
6. Click the "Browse..." button after "Select image file to attach"
7. Click on the image and get the URL.
8. Come back to Islamic Board and insert the url when the message box pops up.
Hope I helped! :).
