No, the example shows the name of the file being inserted into the src attribute of an img tag:

<img src="02100.JPG">
[download]

You haven't posted the schema of the table nor a sample of it, so I don't know what details you keep for each photo.

Note that

<img src="\@\ $ome binary trash, in fact contents of a JPG file">
[download]

<img src="data:image/jpg;base64,..."

This isn't how it works. 02100.JPG isn't the image data, that's the name of the image. If all you have stored in the database is the filename all your photos will have to be in the same directory as the page being served. Otherwise you'll have to prepend the correct path to this variable. This clearly isn't doing what you seem to think it does. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/img.
