Hi xel i have another sample url that might need to be included for further
improvement 

Sample 1. 30 pages
<Https://www.sample.net/galleries/images/0011/0aa/a01.jpg> (1st pages)
<Https://www.sample.net/galleries/images/0055/0ae/a05.jpg> (5th pages)
<Https://www.sample.net/galleries/images/0330/0bc/f01.jpg> (30th pages)

So from my observation there should be 5 wild cards that need to be set on the
sample url given 

<Https://www.sample.net/galleries/images/0011/0aa/a01.jpg> 

Change to:

<Https://www.sample.net/galleries/images/*/**/**.jpg> 

1st wild card 
-numbers
-4 digits

2nd wild card
-number
-1 digit

3rd wild card
-letters
-2 chars

4th wild card
-letters
-1 char

5th wild card
-numbers
-2 digits
