To use .gif, .png or .jpg?

Posted by admin (Graham Ellis), 17 January 2004
I've been updating our PHP course - here's some up-to-date advise as to whether you should generate .gif, .png or .jpg graphics:

The patent [on .gif] expired in the USA in June 2003 (it may be different in other countries - if your concerned you should check) and the .png format really hasn't taken off while .gif has been off the "free use list".  If you're going to be manipulating graphics that include photographic elements, you really should be using .jpg images;  if you're using diagrams or cartoons, we suggest you check what the current supported standards and policies of your web server provider are, and write you code so that you can easily flip between .png and .gif at a later date.

That's interesting,

So, do you reckon that Unisys (was it?) or whoever actually made any money out of gif files?

I bet not.  I suspect they just alienated their customers.

I'm pretty sure that you have the right company there. I don't know whether or not they made any money out of it, but they sure did alienated a  lot of people (very few of whom were probably their actual customers). They also got themselves an amount of publicity, and there's a school of thought that says that any publicity is good publicity ...

Personally, if it wasn't for this business with the .gif I wouldn't have known what happened to Unisys - a proud name from the past in computing; where are Burroughs, Norsk Data, Data General, Prime and the like today?

And where's Wang? Remember all that talk about the paperless office (It was Wang that coined the phrase) and we end up with the Wangless office.

ho hum.
