4.- Take photo with Cam. Resize. Upload to CloudDB. Download from CloudDB. Load in Sprite3. Start carousel.

  • Note that at first the ASD/AppInventorBinaries directory is created, that directory should be created automatically without the need of blocks, in the next versions of App Inventor (current nb189a) it will not be necessary to create it by means of blocks. In that directory the CloudDB file will be downloaded. Read.

  • Take a photo with the camera in landscape (horizontal).

  • Click Button:

  • The obtained photo file will be moved to the ASD directory with the name: foto3.jpg
