Need a wordpress plugin to upload images from URL automatically

Hello guys, Sorry i didn’t know where to post this…

I have a serious problem. Sometimes i need to copy a thread from another website that has over 30 images in it, How can i force my wordpress to upload all of images automatically to my gallery before publishing? It takes like forever to upload all of those 30 images one by one to my gallery and then replace it with original images in my post, I am doing this because the website is going down in a few days and I really need their posts.

Thanks
