i'm reading an article that claims that when you visit a web site that has an image (just a jpg) on it, "there are two temporarily distinct versions of the image - the image on the computer screen, and a copy of the image stored in the cache" I think the distinction would be that the one being displayed on the screen is only "distinct" because it's being displayed from system memory, rather than being 'streamed' from the hard drive. it's NOT true that the image exists only on the web site (and is therefore 'streamed' to your system memory or your monitor), and a totally separate one in the browser cache, correct? Is it: (1) Web Page --> Cache --> system memory --> monitor or (2) Web Page --> system memory --> monitor, with a separate copy to cache? or something else? the reason why i'm asking: i'm investigating a guy who went to some web sites to view child porn. he admitted that. but it's only in his temp files, nowhere else. i'm thinking that the statement from the article i quoted above is making a bad analogy - as if viewing a web page was like looking in a store window - you can see it, but everything remains on the other side of the window. AND, if you want to have a whole discussion about the subject matter of the case, this isn't the thread for it. i'm not typing out any further details.
