It is now possible to upload and store the pictures of your own coins.
When adding or modifying a coin, just drop your picture into the designated area.
(This is available only with the "new" way to manage and display your collection.)
When looking at your collection, you'll see your pictures over the "camera" icon.
You can also see your picture on the new gallery view for "My coins". If you uploaded some pictures, it will replace the pictures from the catalogue. You also have an option to grey-out the pictures from the catalogue to better see your own pictures. That's the place to zoom in and see your pictures in original size.
The storage is currently limited to 500 MB per person. You can control your storage on the new page accessible via the link "Manage my picture storage" next to the link to export your collection on "My coins".
