How can I download images in content?

I just want to download images in content with cURL.

For example: Visit any buzzfeed galleries and see content after title. you will see

1. First content for image <img src="blabla.jpg">
2. Second content for image <img src="blabla.jpg"> in content

Now I want to download that 1. bla bla with image to my server. I think its name "url to file" sorry for my english. Can you please help me? And also can it make with wordpress too?
