Instructions

1. Go to your Shopify admin/settings/files page
2. Open your browser Dev tools, go to the console
3. Paste the content of the console_download_list.js file, and press enter
4. Your browser will automatically fetch each page and download the list with the links of all the files on the CDN.
5. Using your preffered code editor, edit the HTML file by adding each link in img tag.
6. Open the HTML file you just edit in a browser then right click-save as. It will download the HTML file again along with all the images in the location you specify.

Thanks @wasalwayshere this worked perfectly and was huge help!

1. Go to: admin/settings/files?limit=250 in Shopify

   2. I used paste+enter in console (Chrome) to output the list of URLs:

const arrOfImgsSources = [];
for(var i = 0; i < document.images.length; i++) {
    let str1 = "_60x60";
    let img_src =document.images[i].src;
    const isSubstring = img_src.includes(str1);
    if (isSubstring) {
        var clean = img_src.replace(/_60x60/g,'');
        arrOfImgsSources.push(clean);
        var filename = clean.replace(/^.*[\\\/]/, '')
        var clean_filename = filename.split('?')[0]
        //console.log(clean_filename)
        console.log(clean)
       
    }
};
//console.log(arrOfImgsSources);

Copy and pasted to a file named urls.txt, then in MacOS terminal, I ran: wget --content-disposition --trust-server-names -i urls.txt

Then to clean up the filenames:

find . -type f -name "*\?*" -print0 | 
while IFS= read -r -d '' file; 
do 
    mv -f "$file" "`echo $file | cut -d? -f1`"; 
done

Thanks a bunch, this worked flawlessly

Bump; this code has saved me for 6mo+ thank you @wasalwayshere

Clean up filenames part doesn't work on Macos, getting errors for cut -d? as bellow:
zsh: no matches found: -d?

For Macos, use below:

find . -type f -name "*\?*" -print0 | 
while IFS= read -r -d '' file; 
do 
    mv -f "$file" "`echo $file | cut -d '?' -f1`"; 
done
