How do I add images to my cards?


Alt provides our customers the important ability to vault assets and do more with their collection. When you send your cards to the Vault, they will be professionally photographed, valued, and automatically uploaded to your portfolio.

Please check that your image type is png, jpg, jpeg, or gif. We also limit the file size to 10MB.

To upload your own images to assets in your Alt portfolio, follow these instructions:

  • Click into the individual asset.

  • Click the pencil icon located in the bottom right corner of the page.


  • An overlay window will appear for the upload of your file.


  • Click the crop icon to change the dimensions of the image.

  • Click the save icon to finalize the changes.

  • Click 'X' to revert the changes.

For further assistance, please contact us through the supported messenger located in the bottom left corner of your browser or reach out to
