Finder doesn't show Image Dimensions or Resolution

Any updates on this?! I've had this problem forever and really getting irritating. Nothing on the internet seems to explain it or have a solution. This used to work. It is broken!

Hey there, evansdoor,

Thanks for visiting the Apple Support Communities to get help with your Mac. It sounds like the Get Info options on photo files sometimes does not display all of the options expected. We are happy to help.

First, if you have not already, we would recommend checking to see if this occurs in safe mode: How to use safe mode on your Mac and a new user account: Set up users, guests, and groups on Mac - Apple Support

If you still have some trouble, please let us know if this occurs with all files, or just specific ones, as well as whether it occurs with all file types or just specific ones.

Cheers!

Do not expect those Finder Show Preview Options to change the content provided on the Get Info panel. Depending on the source, I have some screen-captured images that show their dimension and resolution, while others do not. I have a 300 dpi image that I created locally in Affinity Designer that reports its dimensions, but not its resolution on that Get Info panel, but does show both in the Show Preview panel in a Finder window.

As I said, not every image will show its resolution or dimensions in the Finder Preview window based on how and what created it. I have some screenshots in JPG and PNG, where the PNG are most likely to not show resolution, but do show dimension.

I tested this over a wide variety of screenshots, both in png and jpg format, as well as other image sources, and I drew the conclusion that jpg images are more likely to offer dimensions and resolution than png images. At least where screenshots are concerned.

As a test, I just took a PNG screenshot of a Finder window, changed the screenshot image type to JPG, and snapped the same finder window. Both shots showed dimensions, but only the JPG showed resolution too.
