Hello Acecob
the picture has to be on the internet
then - when you want insert the picture you press this button
a box will pop up and ask you for the address of the image
using another tab on your browser or another explorer session surf to the image (on the internet) that you want to insert
right click and select 'properties'
a box will pop up with the address of the image - copy that address (highlight the address with your cursor and then right-click and select 'copy')
return to the box asking for the address of the image.
paste the address you just copied over the top of the partly complete address in the box and press enter.
when you have been returned to the editing box you will see the address inside some square brackets with 'IMG' inside them
thats it
you can check where my picture of the Fabulous Hudson Hornet is by right clicking on it and selecting properties - you'll see that the image is on an ebay site.
good luck
