For both PC and Android...there is a pretty simple process....above...between the paper clip looking icon and the smile icon there is a picture window....just click on that and it gives you a link to click on to insert a picture....
What if I get the "Oops picture is too big"
PC....right click on your picture and click on "edit"...it will open a basic picture editor....you can then use the "resize" feature at the top of the screen...and/or grab the edges to shrink the border.....Typically if you shrink a picture until it fits completely on the page it will then be small enough to upload.......(and viewers won't have to "scroll" to view a posted picture)
Android.....Similar process....go into your photo and select "crop".... you can then shrink down the picture and it will make the file significantly smaller so it will upload....If it still won't upload...crop it again.
