When you are at the "Post a reply" page hit the Img button with the mouse and you should get this, [img].%20This%20will%20be%20at%20the%20beginging%20of%20you%20image.%20Then%20go%20to%20the%20image%20you%20want%20to%20post,%20get%20it%20the%20size%20you%20what%20it%20by%20left%20clicking%20on%20it,%20put%20your%20mouse%20on%20the%20image%20and%20right%20click.%20Go%20to%20the%20bottom%20and%20select%20properties.%20Then%20highlight%20the%20address,%20put%20your%20mouse%20on%20the%20highlighted%20address%20and%20right%20click%20and%20choose%20copy.%20Now%20go%20back%20to%20your%20post%20and%20right%20after%20[img]%20right%20click%20and%20choose%20paste.%20This%20will%20paste%20the%20address%20into%20the%20post.%20Now%20go%20up%20to%20the%20image%20button,%20Img,%20and%20click%20on%20the%20image%20button%20again%20and%20you%20will%20see[/img] show up at the end of the photo address.
Here is an example of what it should look like in your post you are writting, but without the spaces in front and behind the Img tags.
I had to put the spaces in so you could see what it would look like. This is what it will look like without the spaces:
PS: Remember the image tag [img]goes%20in%20front%20of%20the%20photo%20address%20and%20the%20image%20tag[/img] goes at the end of the photo address. No spaces at either tag.
