Well, that is correct.
The HTML-"programming" (the so-called "tags" ) are defined by the official W3C Consotium. They define how Internet Browsers should interpret them.
What you call an "infobox" is actually a hack by Microsoft.
Microsoft *never* cared much for standards - they used to define them themselves, in the result oppressing them to the whole world. That "infobox" is just another example.
What you call "infobox" is the "alternative description" of an image. Webmasters *can* include it, but need not to.
According to the *official* rules, they shouldn't be displayed EXCEPT when the picture is not available.
Microsoft is actually breaking these official rules by the W3C Consortium, and implemented them as what you call "infobox" , these small pieces of text floating above pictures (buttons as well, as they are often pictures, too).
So Netscape implemented it according to the official, world-wide standard.
I know for Mozilla (the open-source precessor to Netscape) [Mozilla Firefox in my case] that there exists an so-called "extension" which lets Mozilla actually act like the Internet Exüplorer in that point : It actually shows these things you called "infoboxes". You must download it first, though, but it's only a few KB big. You'll find the way to it through the options, tools, and then extensions.
Alrik.
