Cassini's VIMS (Visual and Infrared Mapping Spectrometer) instrument has started issuing public release images on our website at approximately weekly intervals. Just thought this might be of interest. Full disclosure: I work for VIMS, so yes, this is a shameless advertisement. But we do color good -- it's pretty, and it's real data. If you have specific requests for images or something that you'd like us to work up a website image-release for drop me an email or reply to this post.

The PPJ has always done tiff's - never figured out why.

I try to aviod PPJ when it comes to Cassini releases. For CICLOPS stuff, I grab it off their home page in PNG form, though the server used to die a lot in the past during heavy demand. I get annoyed to see other PPJ releases such as VIMS mosaics blown up 4x and finding the JPEG version is badly artifacted, while the TIFF is several megs in size. For a 250x250 image. Furthermore, I've seen cases of images that were submitted to PPJ as obviously badly compressed JPEG, only to be presented there as a losslessly encoded TIFF as well.

There is generally little understanding by people on the net which format suits which use the best. Things like posting windows dialog screenshots as 150 kb lossy, smudged JPEGs when the same thing comes down to under 10 kb in PNG, lossless!
Ah, rant over...
