However, Socrata assets will have either a standard icon or a preview image generated from the asset. Any derived view that is a chart, calendar, map, or data lens will generate a snapshot image taken from the view. In some instances, the snapshot service may fail to generate a preview image, in which case a generic icon will be used in its place. An update to the view will trigger the image capture process and should generate a new preview image.
For all other assets, including filtered views, grouped tables, uploaded shapefiles, forms and new visualizations, a default image will be used in the featured content.
