[<http://website.com/assets/image.jpg>](<http://website.com/assets/image.jpg>) If the image is not on your domain - go look there for image
[//website.com/assets/image.jpg](//website.com/assets/image.jpg) image loaded using http or https protocols
(For internal use if the image is on the same server)
image.jpg image in the same place as the document calling the image!
./image.jpg Same as above, image in the same place as the document calling the image!
/assets/image.jpg Similar to Absolute Paths, just omitting the protocol and domain name. Go search my image starting from my root folder /, than into assets/
assets/image.jpg this time assets is in the same place as the document, so go into assets for the image
../assets/image.jpg From where the document is, go one folder back ../ and go into assets
../../image.jpg go two folders back, there's my image!
