Grav newbie here . I was trying lightslider plugin .  It is displaying images and text as it is supposed to be but when i set the slider_type : text and i have images with names image-1.jpg, image-2.jpg,image-3.jpg in the same folder,  the images are not loading . The read me says
When in text mode, the lightslider template automatically looks for images of the format: image-1.jpg, image-2.jpg, image-3.jpg, etc. It will associate each section of the page content to each image in order.
Can somebody please guide me on what i have done wrong ?
