xose was awarded the Basic Barnstar by warren for their work in this research note.

In #balloon-mapping, #timelapse, #photo-monitoring and other methods documented on this site, you often end up with thousands of photos -- this activity shows how to upload and share them using

Lots of photos can be hard to upload to the web or share with others; we've collected a few different approaches to this at the Photo Sharing page. Take a look and choose a technique that works for you.  

Pros & Contras using


  • Non profit organization focused on long term unaltered file archiving.

  • Unlimited number of files.

  • Unlimited size of each file.

  • Several formats allowed: images (jpg, png...), video (mp4, ogv, mov...) audio (ogg, mp3, aiff...) pdf, text files...

  • Direct and torrent download autogenerated links.

  • Keeps unaltered original files and automatically generates low res copies.


  • Private publications not allowed. Everything uploaded to goes public.


Step 1 - Get your account

Visit and create your "library card"  


Step 2 - Upload files

Click on the upper right arrow to open the uploading dialog.      

Drag and drop the files you want to upload in the box.  

Fill the required information with the red asterisco and be sure that "Test file" says "NO" or files will be deleted after one month:     Be patient and wait untill your files finish uploading and till your page is created.  


Step 3 - Sharing

Once your page has been created visit  

For the rest of this guide visit this example;  

As you can see there's a "DOWNLOAD OPTIONS" box at the right side of the page. The full information package can be directly shared in two ways:

  • Direct download clicking on "16 ORIGINAL"

  • Via torrent file clicking on "TORRENT". In this case you'll need a torrent downloader like Transmission  

You can also view a complete list of the files contained in the package clicking on "SHOW ALL" and share them individually. Right click on the file and select "Copy link location".

I need to look through the API, but I wonder if it'd be possible to add some of the extra features, or really interfaces, that mapmill tries to provide. I'd been thinking about reworking and debugging mapmill, but the point of its 2.0 was to make it affordable for PL to host so many images. If we could do this via, that'd be so much better.

So, I'm thinking:

  • map view based on GPS Exif tags
  • "Voting" or classification, maybe via the tagging system
  • Really smooth and reliable bulk upload (though mapmill never quite got there :-/) with drag and drop
  • lots of sorting methods, like sorting by untagged (unranked), by filesize -- these may exist already

Maybe even MapKnitter integration? MapKnitter can place images by GPS and compass and altitude, on a map for a first-pass placement.

Is this a question? Click here to post it to the Questions page.

x) Thanks warren! I sincerely don't know anything about their API but that would be awesome! Archive lets also add extra metadata so I think GPS tagging would be possible as well to help Mapknitter to position the composites.

By the way tomorrow I'll give the first try to a kapfoil arrived yesterday. Still virgin with mapknitter but not for so long ;D

This is so great and relevant. Thank you for putting together this helpful documentation!!

Hi, @xose - trying to build out this workflow to generate a map of images if they have EXIF data. It's very slow, but you can read about progress here:

I wasn't able to get GPS EXIF from without downloading the full-res originals... that's why it's so slow!
