Yes, this is possible. For example, you can load multiple images from different dates for change detection. Or images from different sensors and combine features from each image to formulate a final class description.

Ok Thank you very much.
Do you know a tutorial for that?

We did a webinar that works with image to image change detection - please watch the session on Natural Disaster Mapping for Hurricane Harvey. Images from different acquisition dates were loaded to a single project and the water area in both calculated and compared. It is a straightforward example of how to work with multiple images within Developer.
