Question:

I am using Amazing Slider. I wonder is there a possibility to add multiple images at once – or you have to select each image individually?

Answer:

Yes.

In the Add Slides dialog, click the “Add images” button, then you can select multiple images and add them at once.

If you are using Windows, you can hold ctrl or shift key to select multiple files. If you are using Mac, you can hold command or shift button.  It’s just like how you do in Windows Explorer or Mac Finder.
