Block image >1mb

[rfstrider]

Hello!
I'm new here, I'm trying to block large image because the 9hits application doesn't support external extensions.

This is the code I am trying to run:

Javascript:

function blockLargeImageURLs() {
  const maxImageSizeBytes = 2.5 * 1024 * 1024; // 2.5MB in bytes

  document.querySelectorAll('img').forEach(img => {
    const src = img.getAttribute('src');
    
    const fileExtensionRegex = /\.\w{3,4}$/;
    if (fileExtensionRegex.test(src)) {
      const fileExtension = src.match(fileExtensionRegex)[0].toLowerCase();
      const imageExtensions = ['.jpg', '.jpeg', '.png', '.gif', '.bmp', '.webp', '.svg', '.tiff'];

      if (imageExtensions.includes(fileExtension)) {
        const estimatedSizeKB = 1000; // Adjust this value as needed

        if (estimatedSizeKB > maxImageSizeBytes / 1024) {
          img.style.display = 'none'; // Hide the image
          console.log(`Blocked image "${src}" because its estimated URL size exceeds 2.5MB.`);
        }
      }
    }
  });
}

blockLargeImageURLs();

But still the image are still loading when I tried it with Macro Editor,
Also please let me know if you have better idea..

TIA

If you do not have access to the html code of the site, it seems to me that what you want to do is impossible.
And your code just hides the images from displaying, not from downloading, which are two different things.
