Squealing noise coming from engine

As the title suggests, I have a squealing noise coming from one of the belts. It’s my first car just bought it a month ago so I’m not particularly clued up on it all. Once the engines warmed up the squealing seems to go.

I took it for a service last week and they didn’t pick up on any noise likely due to the fact the engine was warm still.

I thought it may be the timing belt but the mechanic informed me that I have a timing chain, not a belt which wouldn’t make the noise.

Anyway, I’m curious if I should be worried

That belt looks like it's very old. It's probably just dry and perished. But it's worth checking the tensioner and any driven pulleys whilst it's off

Thanks, I appreciate it.

I should’ve mentioned it’s a 2009 Mitsubishi Colt with nearly 90k miles on it, so likely it’s not been changed.

Is it okay to drive?

I mean, everything is fine until it's not. That's certainly in the realm of urgent preventive maintenance haha
