Photoshop CS4 Save as Jpeg optinon Gone

Question

Hi,
My photoshop Save as, option for Jpeg has disappeared.. Any info would be great!

Answer 1

I believe the question has been answered above, except that I think there may be some remaining misconceptions out there.
Really, the ONLY thing you have to do, with CS4 and earlier, in anticipation of saving a JPEG is change to 8 bits per color.
Through Photoshop CS4, if you Save-As JPEG with layers or channels or other features JPEG can't support, the Save as Copy feature is automatically invoked to save a flattened version of your file without the extra stuff.
This allows you to save your file as a JPEG as long as the image is in 8 bits before you hit the File menu.  The one thing Save as Copy did not handle was a bit depth conversion.
I normally work with 16 bit per color files.  I often would want to save an intermediate JPEG from the file I'm working on, then continue editing, finally later saving a .PSD at full bit depth.  Unfortunately, because of the above issue I'd sometimes find I'd forgotten to go back in the History so as to continue editing in 16 bit per channel mode!  This is a nasty gotcha!
The really COOL thing is that the Save-As-Copy feature of Photoshop CS5 has now been extended to do an automatic downconversion from higher bit depths to 8 bits.  Thus with CS5 you no longer have to worry about changing the bit depth or anything else in anticipation of Save As JPEG.  It just works!
I have been submitting wishlist requests to Adobe for this feature since about Photoshop CS I think.
THANK YOU, THANK YOU, THANK YOU Adobe for finally implementing it!
