Image resolution
How to set up image resolution parameters and use them for publishing.
You can decide to strictly match your image resolution parameters with the original format of the image file that you import in the Repository. That is, always give file formats the same resolution. That model supports simple publication strategies (few different output formats, no customized post-publish processes), and many complex ones.
However, in situations when output formats use more than one resolution and the resolution pattern differs from one output format to another, it is safer to define your image resolution settings based on the expected deliverables. That is, give image files the resolution based on how it will be published, regardless of their original file format.
