In the right tool area under Images & Documents you find the area for handling the images to be used for training. Here you can load and select the images you want to use for training. When you click on a loaded image, the image will be visible in the Center Screen Area.

In the list of images you have certain possibilities to gain advanced information about the image. If you load a new image only the preview image, file name and type of image are displayed.

When you have started to label an image of a larger data set, a small arrow appears on the left side of the preview image. If you click on the arrow, a list of the images that contain labels will be displayed, containing dimension and image number (e.g. for a Z-stack, Z:400 indicates that the slice number 400 contains labels).

If you click on this information the corresponding image will be automatically displayed in the center screen area. This is very helpful when you are working with large data sets such as z-stacks, scenes or time-series and you want to quickly load the image which you have already labeled.
