...are media which are embedded/integrated in documents without just setting a ressource link. The best counter-example to inline media are normal HTML sites where these media are given as ressource links with different attributes. The following article will refer especially to images by explaining the method of embedding media directly into documents.
As you can see in the example above, the attribute 'src' of the HTML tag 'img' contains a ressource link. The application that analyses the document and the link to the image, for an HTML site normally a web browser, can (down)load the image from the given location. For some reason, it's not wanted or not possible to load another file via the analysing application. One example might be an HTML-email where it's not allowed to attach further files like images. Referring to RFC 2397 and RFC 2557 ('Request for Comments') it's allowed to include the image data ('image stream') directly into documents.
alt="inline image" width="150" height="160" />
The example above demonstrates that the value of the attribute 'src' consists of different parts:
The technique of embedded media (it's a picture in this case) is used in my guestbook on this web page because undesired entries made by so - called spambots (which enter rubbish or advertisement) are to be prevented. A picture is to be created, containing a particular by chance – generated code that must be read off by the user and entered for control, so that the message will be really saved.
The advantages of an embedded picture in contrast to other alternatives arise out of the kind of the generating possibility of the picture and the according HTML-code:
But this method has a further disadvantage: Microsoft's Internet Explorer up to and including version 6.x (the devil's worrisome bother) isn't conform with the upper listed RFCs and doesn't support this method. I don't know how it works with the IE versions 7.0 and higher, but I must admit I don't really care about it. As far as an IE user looks at this article and notes that he can see the picture taken as example, so this is caused by a Workaround by Dean Edwards, which I used here. Those of you who want to learn more about this are to read the information on his webpage.
In this sense: lots of fun with messing around. I have spent lots of time on it, too, until I have had enough of it... ;o)
