Why the image import dialog don't start in the project folder?

If the system wide open dialog for files is selected to a path outside the project folder, the path should be set to the root of the current project folder. Some times I open the import dialog for images and the path is set to "C:\" or "My Files". Images outside the project path are anyway not allowed.

This is the standard OS file dialog and the behavior cannot be changed (afaik). You should get a warning anyway when you try to select a file outside your project folder.

In every program language you call this system function you can set the initial path of that dialog. You have to set it only, If the current path is outside the project folder. That is simple and very useful I think.

I probably misunderstood you, I didn't know that you were talking about the initial path. Yes, I can set that path.
