I just want them to reduce the jpeg compression.

It's virtually eliminated with the calibrated IMG's. What you're actually suffering is chronic impatience.

I'm not going to let people come here and moan about the quality of what MER is putting on the web - period. The JPG's, the PCTDB, the very rapid release of calibrated products on the PDS. MER is the standard to which other missions should aspire. I strongly believe that the scientists are entitled to have their data for a period of time. Giving us SLIGHTLY degraded quality images in real time is a fundamental paradigm shift that has let us come along for the ride.

The compression doesn't matter one bit - for the purpose for which they are intended. They are more than sufficient for the creation of mosaics and animations. How much of a compromise does that compression do to exquisite work like this

None. If you dragged up an IMG version and the rough JPG version of the same mosaic - flicking between the two with the contrast enhanced...you might be able to tell - but why would you do that - their purpose is served as they are - there is no argument whatsoever to suggest that the quality of the JPG's needs improving. To claim that it does is simply impatience and nothing more. If you want to moan about outreach - there is no shortage of missions for which there is a justifiable reason to moan...but to moan about the quality of MER stuff is fundamentally wrong - and it will NOT happen here.
