Question
I am saving images in multiples of 2048X3072.  That is, I have images which are 2048X3072  pixels
                           4096X6144  pixels
                           6144X9216  pixels
               and         8192X12288 pixels

Using maximum quality, indicated as "10" on the save menu, I seem to be able to save all images up to 3x, but get a program error on some images at 4x.  I suspect that images with a lot of fine detail are the ones which give me problems.

My questions:

Are there limits as to the final file size which the jpeg save algorithm can generate?

If I upgrade from Photoshop Elements 2.0, will I get an improved save capability?

Answer
Although I couldn't find any hard and fast material to support my ideas, it's my feeling that you're being limited by your computer, rather than your software.

As far as I know, there are no limits to the JPEG saving algorithm -- but not being an expert in JPEG, I'll refer you to that entry in Wikipedia:

I'm also not sure that upgrading your software would be of any benefit here. As I mentioned, I think the issue might lie more with your processor. I tried to replicate saving a file with your largest specs, and although I'm using Photoshop CS, it worked -- albeit slowly -- and I have a dual processor 2GHz G5.

So to answer your questions: As far as I know -- no, and no.

Hope this helps!
