whosdatsun,
Here is how I post pics -
hit Img above on the menu across the top.
Go to your web site for where you have up loaded your pics - sorry cannot upload straight from you home computer.
I use flickr
On flicker find pic/photo
Click on share image
Select size
Click on HMTL and copy the way to long url for the photo -
-- <a href="
https://www.flickr.com/photos/113742723@N07/11827232196" title="Wow, now isn't that looking nice! by Li'l Truckie, on Flickr"><img src="
https://farm6.staticflickr.com/5510/118 ... a2c5_s.jpg" width="75" height="75" alt="Wow, now isn't that looking nice!"></a>
The part you want/need of whatever all of this means is what I have bolded, so from the
https://farm6 to the end .jpg all that computer speak before and after can be deleted or simply not copied over.
So you can paste the entire url for the photo in between the

and delete what is not necessary or only copy the
https://farm6 to the end .jpg on the flickr photo page.
Or at least that is how I work my photos and it looks like this for micro small -
or this for large ++++

hope this helps.
