First you have to have your pictures posted somewhere on the net.
I use the MSN web site. They allow you 3M of free space and then you have to pay for more storage.
There are others some free others you have to pay something. Also what web provider do you have? They might have some free storage for you also.
Once you have pictures on the net, click on the picture icon in the post reply screen. It's located in the second row just below the "s" with the line through it and above the frowny face. Open another internet screen go to your picture post area. Hi light the picture you want, rignt click on the picture and go to proporty. There you will find the http address. Hi light and copy then come back to this sight and paste between the "
" you'll get when you slect the image icon.
