Hello Kansas, I am not sure that which you are asking but I do this:

If I wish to put a photo into a post I use mouse to 'right click' on the photo I
want from PC (Psychcentral) and a menu comes up 1) Save image as.
2) copy URL
3) Copy image
4) Open image in new tab
__________________.
Inspect element

for grabbing one from PC do the right click, menu choice "copy URL"
and then go to your post, type the post and when you reach the place
to insert the photo type " "

do not include the spaces i have or the 'quotes'.
when you hit the ~submit~ / or post quick reply; it should, if I have instructed you properly,
put your picture desired in there.

If you are getting your photo from another source, right click on the image
and choose "open in new tab" then do the same procedure of copying the URL
and doing the same for creating your post.

I hope this was of help.
