If you have difficulty uploading photos try imgbb.

Quite a few here use it including me. It's free, easy to use and no account is needed.

Don't forget to select 'BBCode full linked' from the drop down menu. Hover your cursor over the box below and 'copy' will show, left click on it and you can then paste the image into whatever page you like with another left click.
