* files (since these are the files that can be viewed in a browser) and creates
|
|
* a slideshow with it by allowing to go to the next/previous image.
|
|
* You can also have a quick overview (thumbnail view) of all the images in
|
|
* that particular folder.

|
|
* (not present) 2. the function resize_image that handles the image resizing
