  • You have tagged this with java, but this looks more like PHP to me. – Mark Rotteveel Oct 07 '20 at 20:08

When an image's link starts with a data:, it means the image is loaded into the page from a MySQL Database. The image gets directly added to the page from the Server's SQL Database and not via a picture file in the server.

  • That's not the complete story. When there is a `SRC="data:..."` what it means is that the image-file, itself, is converted into what is known as **Base 64 Encoding** - _which encodes the `bytes` of the **image-file** into a subset of the **ASCII** character set_ so that they may be 'printed' into an `'.html' File`. There are numerous Stack Overflow Answers about Base-64 Image Encodings inside of `'.html' Files.` Just do an SO Search for "Base-64 IMG Element". Also, the **image-file** is being loaded from some where, but that could easily be Java-Script, among other loading sources. – Y2020-09 Oct 04 '20 at 21:31
