detecting images in web pages

MrNuked

I'm developing a piece of software that needs to detect images in web pages by going through the text. It already detects images that are displayed in the normal html manner of using the img tag. What I want to know is if there are any other ways of displaying images in web pages apart from using the img tag, and if so, what are they?

Well, there's the CSS background-image property. Its generally used for presentational images (like site banners for instance) that don't need to have alternates for accesibility puropses.

there is also the HTML attribute background="" used with the body, table, tr & td tags and the form input object where type="image"
can't think of others but there possibly are

Thanks!

there's also the CSS pseudo classes :before and :after . Not supported by IE, but they can contain image data.

And you can change images on the fly using javascript, vbscript or perlscript ... plus don't forget javascript based CSS (as opposed to text based CSS).

Thanks again for further info.

Another way is graphical input controls on forms.

And Applet and Object Tags could be used too.
