grabber program. How to download if 403 with access?

Question

Images

Hello.
There was a need to download all the photos from the site. The folder in which the images are located is known, the names of these images are unknown.
Maybe someone knows a program or another way to download pictures by mask ...?
Access to this folder is not 403 Forbidden, but images (value name) are opened.
It is necessary that the program or tool search for something like this: site.com/folder403/*.jpg where * is any file name, the main thing is that it is .jpg
Help please.

In general - no way, if the server does not give this list - you will not be able to find out without having access to the server's file system directly. If the file names have some regularity, you can enumerate all variants of names that fall under the regularity.
