Excel hyperlink download issue

Thank you for reading

My objective is to be able to mass download images via hyperlink.

I have an excel file that has all the links to the webpages that contain the pictures I need to download. So, I save the excel file as a webpage so that I can use a program like downthemall to go to each image and download them, here is the problem. When downthemall downloads them it only downloads them as a .htm file. However if I click on each link, it does forward me to the site and the picture does show and I can save the image manually. I am trying to figure out a way to be able to download all the images without having to manually click each link, as I have almost 2k images needed to download. I also wanted to add that you have to log into the webpage that the links are forwarded too. Any help would be greatly appreciated. Thank you for your time.
