all I have to do is select "attachments add a file" and this takes me to the main file pages of my computer.
I find my photo, right click on it, this gives me a sub category command list and I left click on "select".
This automatically transfers my photo to the post. I repeat the process to add additional photos. When I click ADD to grab another photo, the computer goes directly to the same file holding the previous photo so it's a good idea to have your project photos in specific file folders so they are easy to find.
