High res images no importing correctly

1

Hello, I am trying to import some images into flash. In other programs the pictures look great but when I import into flash they look unstaurated and gross. I know photographers use flash for there portfolio’s. So whats the secrect. I have tried saving as a Tiff, Jpeg and bmp all change when brought into flash. Plus when I click on the imprted image in flash it come up in the property window as a bitmap? Any suggestions, thanks so much for your help.
