Here you control the target of the load images process.
A Target may be selected from the most recent list of targets, or selected from the folder hierachy of the Image Archive, or you may create a new folder.
If the source images are in a folder hierachy it will be copied to the target. Would you like to store all images in a folder, deselect "Match folder hierachy of source folders".
Click on the "Load" button to start the loading process.
