Image Url Data Type. Unlike the fixed size char data type varchar does not store any blank characters when the full length of the field is not used. Data uri in a html image src property is not supported by ie edge.
Data uri in a css background property is currently supported by all major browsers and safe to use unless you care about ie7 and older and it that case you can add fallback background image property with path to ordinary image file for ie. For example you can capture alt image the description for an image or the actual url behind a link and add that to your captured data. Unicode data uses the unicode ucs 2 character set.
Image examples display youtube thumbnails.
There s no shortage of content at laracasts. Use nvarchar max varchar max and varbinary max instead. Ntext text and image data types will be removed in a future version of sql server. This really depends on your use case see below but storing as text has performance issues and a huge varchar sounds like overkill for most cases.
