well i hdri'ed an image, and it will only tone map as a 16 or 32 bit image. The problem is i can't save the image as a JPEG. it will lemme save as tiff, psd, ect. i have cs3 btw. can someone help me or tell me how to convert these 16/32 bit images to jpeg?!

 

after you have mapped it. change the image mode to 8 bit to save as jpeg. hope that helps.
