Like most - I'm now HiRISE obsessed - so I'm often finding myself trying to load images that are 10-20k on a side.

The large Victoria JPG - the 25k x 34k 'red' filter image I found would not load in Photoshop, Imageready or Gimp - and others have cited similar problems...I've found an answer..

www.imagemagick.org ( and for me - specifically http://www.imagemagick.org/download/binari...windows-dll.exe )

I installed that and simply doing convert red.jpg red.png - gave me a 500mb PNG of the 200 odd MB JPG which Photoshop loaded very quickly indeed.

I've tried comparing some of the smaller PNG's and JPG's from the HiRISE team and there is very very little difference - for the sanity of the HiRISE server, your own hard drive and bandwidth useage in general, my plan is to use the JPG's where possible, and if they're too big for photoshop, use Imagemagick to convert to PNG, and in some cases simple convert a subset of the image to PNG ( i.e. from pixel x,y to pixel a,b only )
