    Uploading your pictures directly into the cloud

    Yesterday I found some time to make an example of image push to the Cloud using Seafile storage. The idea is that instead of making a regular file upload that needs some kind of Backend gallery to preview the pictures, we can have a different take, like pushing the picture directly to your Cloud-storage. WiFi…
