Re: "Image resolution" - how would you interpret it?

It really depends on the context, and what other information is available.

For example, someone shows you an 8x10 print.   If you ask for resolution, they may give you the dpi, and that will be enough - because you know the print size.

When you still have the image as a file, resolution most commonly means the number of pixels.

But at its most basic, resolution is often the size of the smallest detail that can be discerned on the image - sometimes in combination with distance.   I.e. 'this satellite image has 10cm resolution'
