Just as an additional test, I transferred one of the images that fails to save as JPEG to my laptop and tried to save as JPEG there. The same problem occurred. The Laptop runs WinXP Pro, 512MB RAM and 60GB drive.
Can you NOT send the files as native PSD or TIFF?
What are you trying to achieve by using JPEG compression?
My Printer wanted them as JPEG’s. I’m able to save as TIFF or PSD, just wondering why JPEG is broken for larger files and why nobody seems interested in addressing it.
Because nobody else is seeing the problem….
I’ve searched the forum for this problem and have found several instances, yet no one seems to get the problem fixed. It seems people just lose interest in it.
Sigh. Don’t even try it. Post the links where you found this problem in this forum.
No one is losing interest. Chris Cox has replied – look at the splash screen when Photoshop loads – read the names. You have "GOD" replying to your note.
You have a system specific issue that is probably resolvable, but there is not enough information to do so.
My Printer wanted them as JPEG’s
He’s an idiot. Find a printer that uses a file type that does not introduce artifacts and loss of data – should be your first clue. From the Cymbolic web site:
* The software accepts PostScript (RGB/CMYK) and TIFF (RGB/CMYK)
the more detail in the image the more likely to fail
Means nothing. Do mean more pixels – Resolution, color, what? Photoshop doesn’t read "detail".
but the resulting file gives the "invalid JPEG marker" error when trying to open
When trying to open in what? Photoshop? The file is becoming corrupted, and it’s not photshop doing it. It’s likely your hard drive. Have you tried opening it in any other image viewing program like ACDSee or Irfanview or MS Photo Ediot (intentional misspelling)?
changing available RAM to PS
Should be set to 70-75%.
using the JPEG2000 plugin (when I use that PS just exits to the desktop without warning).
Can you use the plugin on smaller files reliably?
These are files going to my printer to be printed at about 30×40 inches on a lightjet at 300dpi so they need to be this big
What JPG settings are you using for compression? What is your original PSD or TIFF file size prior to trying to save it as JPG?
I opened an existing image that was 30 megs at 300 ppi. I resized it to 30 x 40. I duplicated the layers until the PSD was just under a gig. I saved this as a JPG with a compression setting of 12 and still could not get a 500 meg JPG. More like 30-40 meg JPG’s.
Something’s wrong or you’re not telling us something. In order to get a 250MB JPG, with a quality of 12 (the least amount of compression), you would have to be over the 2 gig file limit of photoshop.
Nah – I can get a 250 Meg JPEG just with a really textured (noisy) image.
Well, I can’t, I’ve been trying for about an hour. What size is the source PSD that gets you a that size of a jpg? If JPG acheived only 50% compression, that’s a 500mb PSD – reasonable, except I’ve never seen lossy compression produce that poor of a compression ratio.
Point remains that A)if it’s about getting the job done, it TIFF will be fine, and B, there is something not right in Denmark (as the saying goes).
It seems people just lose interest in it.
especially the posters. i think we’re supposed to keep on working this out amongst ourselves. :/
" My Printer wanted them as JPEG’s"
"He’s an idiot. Find a printer that uses a file type that does not introduce artifacts and loss of data – should be your first clue."
This is the best bit of advice in your entire reply, Tony!
:o)
In response to your reply about saving large images as PSD’s as opposed to JPEG’s,some of us do not want to burn the hard disk space that it takes to save large images as PSD’s. A couple hundred megabytes per image is not trivial.
I suppose I would feel somewhat better if I hadn’t been successful with this option for a couple of years in the bundled "Limited Edition" that came with my previous PC!
If Photoshop screws up it’s own saves then I’m hugely disappointed.
System is P4 2.1GHz, 768MB RAM, Photoshop 7.01. Trying to save images scanned with Nikon 8000 ED. Not trying to save to, for or from the Web…just to a local hard disc.

Hi Jeffery,
Did you ever get a satisfactory explanation for this problem? I, too, am seeing the same behavior you report at about the same size image. So far I have not seen any replies that set my mind at ease. Someone by the name of Chris Cox is trying to assure me that the problem isn’t in PS, but that’s the only app that has been in contact with these images. [Pentium 4, 2.1GHz, 1GB RAM, Win XP Home, 30GB HD available]
Thanks,
Marty McGillivray

read the splash screen next time you start photoshop.
