The complete electronic text of an article is called the full text.  Some databases, like Electric Library and Academic Search Premier, provide entire articles online (though usually not the images).

What if there are pictures or graphs with the article you want to see?

To find pictures originally published with the article, you usually need to get the print copy from the library. There are a few databases, however, that provide full content. Full content is the electronic version of all the entire article including graphs, charts, pictures and text.
