Wish: Show the next picture with the same tags as previous picture already selected if user has this setting set to on

Trello Card

One way of uploading and tagging litter in a very fast way,
is making sure that you have seperate folders on your laptop with identical litter-items.
For instance a folder with only balloons, or only waterbottles etc

The next step is to upload all of these items on web and then start tagging.
At this moment there is already the functionality that the tags that you already used are shown as possible tags, so you only have to pick one of those.
However, if you have a folder with (for instance) all Heineken beercans,
you still have to select 'Heineken' from that list and also 'beercan' from that list and then submit.

If you use this way of uploading as i do and you have to tag 100 of Heineken beercans, that means 200 extra click, which is a 'waste of time'.

So extra wish:
A user setting that says something like 're-use the tags from previous picture' and if that is set to True:
after submitting picture 1, not only show the next picture but also automatically select the same tags from the previous picture.
As a user i can check these (and a the amount for instance or add some extra tags if necessary) and then press submit.

And again, in the next picture, you show the same tags as in this last-submitted picture, until the user sets this setting to off.

Start by reviewing the issue and closed pull request #306, then trace the web upload and tagging flow and the user-setting entry point. Done means an enabled setting carries the last submitted picture's tags to the next picture until disabled, while still allowing tags to be checked or changed before submission.
