I would echo agreement with Bevi's 'pattern' here, and have suggested it
in the past as a best practices guideline. Additionally, I 'wrap' the alt
text in [square brackets], for times when images might be disabled for
sighted users, and the image 'interrupts' or skews text flow (or might
seem redundant to some users). For example:

[Photo: Jared Smith] Jared Smith is the Director of WebAIM...

As opposed to:

Jared Smith Jared Smith is the Director of WebAIM...

Just a suggestion however.

Yup, some common identifiers I use are: [Photo: ], [Icon: ], [Graphic:
], [Chart: ], etc.
