For all non-DICOM type of image data the loading use the AUTODETECT loading page. The dialog looks like below.
Most of the functionality is common with the File based loading.
Additional functionality is added in the bottom line for the Selected Files images: load the image(s) directly or with Operation in one of the modules available in the selection list (highlighted with red rectangle in the capture above). To load the image(s) directly, select the module with the left mouse button, for example View in the example above. The list closes, the button changes to the new option, and the button operation is executed: the image is loaded and visualized in the selected module. The with Operation button starts loading the image series in the module that was last used for direct loading. It opens a dialog window for specifying pre-processing options as described in Image Data Transformations during Loading
