The easiest way to post an image on the phone is to use a site like
Postimage.org - free image hosting / image upload. Choose the image from the phone by clicking browse and then click upload it. Then when done copy the box that says direct link. Click the image icon box in the message field on this forum. Paste the entire link in the field. Make sure the http:// that was there is deleted. (It is simply an example of what the link should start with). When done, click OK. It should show a code. Do not delete this, it will appear as the image.
