Well, i made those pictures with a photoshop-plugin and if you are able to look at them then you will see that they show the effect i described. But maybe you don't see it as you can't watch jp2/j2k files?
Anyway also if you google around you will find enough picture comparisons where these effects are shown and discussed.
To say that jp2 is the cure for online games is total nonsense as most of the online games are flash games which use vector formats gfx out of the box and if you're talking about the second biggest platform shockwave than also here flash graphics are included (on the fly converted to textures if neede for 3d) or the most common img-fileformat jpg is used. And if using shockwave compression on pictures all so defined pictures are compressed to jpg no matter what they were before. Music is by far a much greater memory eater here as there only exists one mod-tracker xtra which has to be bought seperately and also downloaded beside of the plugin. Here you could spare much more memory.
