If PC I'm able to download it using IDM (grabber wizard using wild card
method)

Let's say comic name is io and it has 20 images and the target URL is:

<Https://www.asd.net/io/images/001.jpg>

so on IDM the wild card setting should be 

URL => <Https://www.asd.net/io/images/*.jpg>
wild card => 000 
wild card type => numbers (choose)  letters (choose)
pages => from (000) to (020)

And it will try to grab any link according to the wild card settings.

Unfortunately I did post the same topic but so far they haven't reply yet.
This function is already exist 10 years on IDM yet httrack still not has a
stable settings let alone to put it on android.
