These rules should be used for websites only. Journal articles, even if they are found online, should still be cited as articles. Drug information sources such as Lexicomp and Micromedex should be cited as DI sources.
The standard format for citing a website is:
Author(s), if given. Title of the webpage [Internet]. Publication city, if given: Publisher, if given; Year published [cited year month day]. Available from: URL.
When citing webpages, it is important to give the date cited -- this is the date that you looked at the webpage. You should also include the date the page was updated, if relevant.
Determining the publisher of a webpage can be difficult. Sometimes it is obvious (WNE.edu is published in Springfield (MA)) but sometimes not. Look at the very bottom of the page for contact or copyright information; usually you can find it there.
When there’s no year of publication, you can use the copyright date. For example, a website with a copyright date of 1995-2021 would be cited as c1995-2021, making sure to include the ‘c’ to denote it’s the copyright date.

Images found on the internet should be cited as a "part" of the website from which they come. Begin by citing the website normally as above, then adding the information specific to the image (in red):
