A convenient way to do this is by converting the binary data into a Base64-encoded string and using it as a data URL in HTML. Best suited for small thumbnail photos or icons. Storing Images in SQL Server Images are often stored in SQL Server as VARBINARY(MAX) columns. For example, a table structure for storing user photos might look like this: CREATE TABLE UserPhotos ( UserID INT PRIMARY KEY, PhotoThumbnail VARBINARY(MAX) ); Converting the Binary Data to a Base64 Image URL SQL Server doesn’t provide built-in functions to encode binary data as Base64, but we can achieve this using FOR XML PATH combined with BINARY BASE64 . Below is a query to transform the binary image data into a Base64 string formatted as a data URL: SELECT CASE WHEN p.PhotoThumbnail IS NOT NULL THEN 'data:image/png;base64,' + REPLACE( RE...
