Duplicate content between Opening Files chapter and Files Menu
There is a lot of duplicate or very similar content between the Opening Files chapter within Getting Images into GIMP
and the descriptions of the commands in the File menu.
We should rewrite the Opening Files chapter
to reference the information of the respective file commands where relevant.
There are now also several short paragraphs that have their own help page. For ease of reading it would be better if they were more concentrated on one or a few pages.
The information about specific file types should probably be also moved to either the menu file open command, or to the dialogs section.
One issue might be, how to ensure that unchanged content that gets moved, doesn't need to be translated again.
