The lightbox gallery allows us to add images to the course in the form of a gallery. To add this type of resource, we just need to select it and provide a name and a description. Once added to the course, click on the resource to access it and add the images you need in Add image. 

These images can be uploaded one by one or by using a zip file.

Once uploaded, you can view them and even have options to modify them. Activate Edit mode and for each image a dropdown will appear with these options:

• Caption: To add a caption to the image. By default, it is the file name.
• Delete: as the name indicates, to delete the image
• Flip: To flip it vertically or horizontally
• Resize: Scale the image
• Rotate: Rotate it 90, 180, or 270 degrees
• Tag: Add tags
• Thumbnail: To edit which part of the image is shown as a thumbnail
