What is the method for creating a sequence of URL gallery between two numbers?

I am facing a problem with downloading a large number of galleries. Although I know the name of the last image file in the sequence, I am uncertain how to create a series of image links that I can use with a download manager. Currently, I have the HTML links in a text file in brackets, enclosing the first and last images. For instance:

http://www.example.com/manufacturer/csg/img_[001-018].jpg
http://www.example.com/manufacturer/pae/img_[001-014].jpg 
http://www.example.com/manufacturer/lucid/img_[001-010].jpg
and so on
I am looking for a way to generate all those links based on the numbers in the brackets without creating them individually. Can you suggest anything?

While searching for a potential solution, I came across the below JavaScript code. However, it can only generate the sequence from user input of the first and last image, while my links for each gallery are distinct:


var fso, f1;
fso = new ActiveXObject("Scripting.FileSystemObject");
f1 = fso.CreateTextFile("URLs.txt", true);

var i,j;
for (i=0;i<5;i++) {
f1.write ("http://www.example.com/gallery/img00" + i + ".jpg\n");
}
f1.close();

You can use a tool like Bulk Rename Utilityto generate all those links based on the numbers in the brackets without creating them individually. Here's how you can do it: 1. Download and install Bulk Rename Utility from their website. 2. Open the tool and navigate to the folder where your image files are located. 3. Select all the files you want to rename. 4. In the Bulk Rename Utility window, click on the Add button and select Insert. 5. In the Insert dialog box, enter the starting number of your sequence in the Start field and ending number in the End field. 6. In the Insert dialog box, enter your desired file name in the Text field followed by a square bracket and a number sign (#) that represents where you want to insert your sequence number. 7. Click on Preview to see how your files will be renamed. 8. If you're satisfied with the preview, click on Rename to rename your files. I hope this helps!

Yes, you can generate those links using JavaScript. One approach would be to use a regular expression to match the number range in the brackets and then loop through that range to generate the individual links. Here's an example of how you could implement this in JavaScript: 
// Define the base URL and file name format
const baseUrl = 'http://www.example.com/manufacturer/';
const fileNameFormat = 'img_{0}.jpg';

// Define the list of links with the start and end numbers in brackets
const linkList = [
  'http://www.example.com/manufacturer/csg/img_[001-018].jpg',
  'http://www.example.com/manufacturer/pae/img_[001-014].jpg',
  'http://www.example.com/manufacturer/lucid/img_[001-010].jpg'
];

// Loop through each link and generate the individual image links
linkList.forEach(link => {
  const matches = link.match(/\[(\d+)-(\d+)\]/);
  if (matches && matches.length === 3) {
    const startNum = parseInt(matches[1], 10);
    const endNum = parseInt(matches[2], 10);
    for (let i = startNum; i <= endNum; i++) {
      const fileName = fileNameFormat.replace('{0}', i.toString().padStart(3, '0'));
      const imageUrl = baseUrl + link.replace(matches[0], fileName);
      console.log(imageUrl);
    }
  }
});
In this example, we first define the base URL and file name format that is consistent across all the links. We then define the list of links that we want to generate the individual image links for. We loop through each of these links and use a regular expression to match the number range in the brackets. We then loop through that range and generate the individual image links by replacing the number range in the original link with the individual numbers from the loop. We log each generated image link to the console in this example, but you could modify the code to write them to a file instead.
