Nova size n format for pictures

I know this has been asked amount a million times, so sorry....
I need to know what format to sprites, landing pic, etc have to be in order to work.... I've uploaded a pack with 18 planet graphics on my website, all in jpeg, so i hope they have to be in jpg!

I need to know the size and format of:
Ship description picture
Shipyard thumbnail
comunication picture
target picture
Max planet size
Planet description picture
outfit picture

There's a long thread that answers most of your questions (url="http://"http://www.ambrosiasw.com/webboard/Forum9/HTML/002373.html")here.(/url) For stuff like "maximum size of spöb graphic," I don't know that it's ever been established. I know SFA has some spöb graphics that are larger than the Jupiter graphic in the Nova Scenario, but they really slow down frame rates.
