Q: I Have  a timer symbol on the side of my album. What does that signify and how to get rid of it ?

Not sure what you are seeing

the badges for Photos are in Photos Help

Display titles, other metadata, and badges

Photos can display the title you assign to photos in the Info window, metadata (other information about each photo, such as its file type), and badges that identify whether the photo has been edited, had keywords added, and more.

• Set Photos to display titles, metadata, or badges: Choose View > Metadata > [Metadata name].

Provide a screenshot of what you're seeing.  Never heard of an icon on an album.  Images can have one of these icons for various reasons:

But there's no "timer" icon among them.

I Have this same symbol but it's on all my photos On the bottom right corner, it's counts to where the 15 minute marker would be and stops.
