about dcmgpdir and dicomdir

[dcmtk_Beginners]

Hi ，
I have a lot of questions about the dicomdir...
The first is to make dicomdir, dicomdir document which contains general information on the fourth floor, according to patient-study-series-image of the order to organize, but also added some functions of the thumbnails, so dicomdir is based on patient-study - series-image-icon in order to organize, what is icon? is it the compressed image of original image , how to do it?
