What about my desertification pictures?

For some weeks now, I am not publishing pictures about our successful projects in the combat of desertification anymore. Why? Well, simply because I encounter always the same difficulty : upload of pictures works, but sending the uploaded picture to the editor of WordPress fails.

I have been checking to find a solution, but seemingly other people encounter the same problem.

Could WordPress solve this problem? I hope it. Meanwhile, stay patient, because I have some splendid things to show!
