Global Thumbnail View
By default data is displayed in a hierarchical manner. But you can view images as thumbnails by selecting the Global Thumbnal
view from Data View
in the Navigation
column. You can choose the display level as exam, series, or image.
You can select multiple exam, series, or images (depending on the scope initially chosen) and apply labels to several components at once.
Example with several series selected to which the same label can be applied simulatensously.
