(if you are copy and pasting an image from a website (i.e. not one of your images just anything off the web)
... see the img box when you go to make a post ...
just highlight the url
copy and paste into your post
highlight the url and then click on that img box
then preview your post before submitting to check the image can be seen correctly
and submit.
