Alternatively, images files can first be just referenced by
using the Image File Linker what is much faster and doesn't
require to convert all images first into the KNIME internal representation. The image are then only read on demand, e.g. as
soon as they are displayed in a table or view, or if subsequent
nodes request them. To explicitly import the referenced images,
the Image Importer node can be used. The main use case of the
Image File Linker is to save hard disc memory when processing
a lot of images in loops (see the KNIME loops in Section 2.2).
