When using the photobucket, use the bottom link and just paste it into your message box here by pressing ctrl and the V button.. You don't have to click on the picture box where the mountain is.. At least that is the way that I do it.. See photo below on which link to use for photo bucket..
Where the arrow is .. is what I copy just by clicking on the link and then I come here and on my key board i just hit CTRL and the V Key together where I want the image to show up an there it is...
