How to copy an image url into a block?

Hi, I just want to know if there’s a way i can copy the url of a texture into a block somehow in the resource pack editor. i just don’t feel comfortable downloading a bunch of pictures onto my computer, if there isn’t a way then this can count as a suggestion

Yes, just paste the url in the browser file opener window.
Websites have some limitations, so a page can not directly load another site image and edit it, you need to load it from the same domain, I would need to create a proxy on my webserver or you can just use the browser open function, it will download the file on a temporary directory.
