@matmarex Well, right now, I've no images to upload. It seems we'll have a sunny day on Friday. I'll have my usual 80 miles trip with my camera and will upload the results on Saturday. Thank you for your action.

@matmarex : Already tested ! It works and I'm so shame not to have tried it ! ;) Thank you so much... and I'll stay with Upload Wizard ! And sorry too for having moved so many people...
Maybe we can remove our comments ?

@Aklapper : I'm uploading images since nearly 10 years, first on 08/25/2006 ([https://commons.wikimedia.org/wiki/User:Henry_Salom%C3%A9 my user page). Ich verstehe daß Sie das für die neuen Benutzer gemacht haben. Ich werde nach "Upload your own work" zurückkehren.

Step : Describe
Previously, we could type the name of a new category for the uploaded file, the uploader answered something like : "Category not yet used" but the category was accepted and we could create it after the uploading.
Now, since today, a new keying box is proposed with categories aligned horizontally (instead of several boxes aligned vertically) and the only categories accepted are existing ones.
For instance, for several photos of a church, I could key the category "Our Lady church of XXX" (not yet used) and copy it with the "magic" copy tool in the description of the next photos.
Now I had to create first the category in a new tab and come back to the uploading tab, key the category for the first photo and copy it with the "magic" copy tool.
