There are two ways, one is to save the binary on file (which is not interesting) and another is to add to the src of the tag img stating that it is a binary. To do this, simply add data:image/jpeg;base64, followed by binary code.

That is:

<img src="data:image/jpeg;base64,<?= base64_encode($binary) ?>" />

Depending on how you saved (in rare cases) base64_encode can be omitted
