Posting your picture here is quite simple.
To start with have your photos on your desktop and named so you can recognize the file name later like Photo1, Photo2 etc
1) make sure you clicked on the "Go Advanced" button (see first attached image).
2) next click on the paperclip symbol (see second attached image below).
3) once you clicked on the paperclip the drop down window will open (see last attached image below).
Now simply select your files from the desktop Like Photo1, Photo2 etc then click on "Upload"
and you are done
Should your photo files be too big you can reduce them in size here for free;-
Good luck with the sale, nice car BTW
