You can display Cards images sourced from a BLOB column.

Cards have declarative way of handling BLOB column value and display as Media or Icon images. You can change the display of the image declaratively by position, appearance, or size using cards Media. If you want to display the image smaller, you can display the image as Icon.

When BLOB column is selected for either Media or Icon, Primary Key Column is required to fetch the BLOB. Also defining Last Updated Column as part of BLOB attributes is recommended to cache the images in the browser to improve the performance and reduce the latency.
