DPI is meaningless if image dimensions are not specified.
Apparently, the default resolution is set to 200 DPI and greatly reduces my image resolution. Please consider in the future setting the default to match the original image quality. (I learned from another user to clear the DPI field -that should be the default.)
This way: While experienced users will know if they want to reduce resolution, beginners won't find out after a lot of work that their high res images are now very low res and they have to hunt down why this happened and then start all over again. I just wasted three hours of editing to get 1MB images!
