I imagine the process as being similar to how you would currently add a file. Now: Your friend messages you "Here's another pic from Paris xxx". You click on the picture, "Save as". Your file system comes up, you navigate to benjammer/travel/paris/pics. You can see the rest of the pictures from Paris in the directory. You hit save. With tags: Your friend messages you "Eiffel Tower :-)". You click on the picture, "Save as". A list of your tags comes up for you to select some. On the other side of the screen are the files that match the selected tags, so that you can see what company your file is going to end up in. They're shown in the order of how many files they tag (that also have the tags you've already selected). The "benjammer" tag is selected by default, as is "picture" and "png" (because your application knows it's been given a png). The "Paris" tag isn't at the top of the list so you type it in and select it. Now "Travel" is at the top of your list of tags, so you add it, along with "June 2017" and "Europe".
