The point I was making is that he does have legal recourse, wheras I got the impression you were saying he didn't- or he needs to prove damages.
Whether or not it’s practical or worthwhile to pursue available legal remedies is something for the OP to decide.
You also don’t need an attorney to send a cease and desist letter. I simple letter that says: I was terminated from the band XYZ by you on xx/xx/xx. I have become aware that you are using a picture that contains my likeness for commercial promotional purposes of band XYZ. This letter is to formally notify you that I have not given my consent nor have I been compensated for the commercial use of my image by you or the band XYZ and I am requesting you cease all such use immediately. If you continue to use my likeness without my consent I reserve my right to pursue legal action against you for doing so.
That’s enough to put the BL formally on notice. What happens after that is up to the OP. And his wallet.
Personally, I think it’s a total waste of energy and time. So were it me, I’d just let it go. It’s not worth the aggravation for something as minor and petty as that. But that’s me. I’ve quit a few bands where I had songs I co-wrote and tracks on demos I recorded get attributed to someone else. My attitude was: “Enjoy it guys. There’s plenty more where that came from.” (If the song went platinum I might have felt different. But lets deal with reality. They were just originals tyat were played by local bands. Besides, most of those bands were gone in a year anyway.)
No attorney in his right mind would take this case.
I have some experience with small claims court, Justice Court as it is called here in Texas. OP would never be able to prove damages/losses. OP would lose the court fees and waste 20-30 hours of his time. Judge would laugh at him after he left the courtroom.
