incompatible jpg standards

Powerpoint97 (and undoubtedly the newer versions as well) can save a
Power Point Presentation chart as a .jpg image. Recently, I've noted my
PowerPoint97 has changed the way it saves .jpg images.

When I save a chart, it saves two files, both of which have a .jpg
suffix. One is the file I expect with the specified name and a .jpg
suffix. The second has the same name and suffix, but a ppTmp prefix.

The second file is: (1) less than half the size of the "normal" .jpg
file, (2) can't be opened with older applications such as "Microsoft
Photo Editor 3," but (3) seems to contain all of the information when
opened with the current versions of Microsoft "Picture and Fax Viewer,"
or Microsoft "Digital Image Pro 10."

An example of a file saved in this format can be found at:

If I seek to open the above file on the computer that used to generate
it, it opens.
If I seek to open the file directly from the Internet with another
computer using IE, it will not open.
If I move the file to another computer, and seek to open it with IE, I
can't.
If I move the file to another computer, I can open with Microsoft
Picture and FAX viewer.

Has my copy of the PowerPoint application somehow been alterer, perhaps
through a Microsoft update, to save images in an additional format. HOW
CAN I TELL if this is the new jpg format Microsoft began promoting in 2000?

================================
IrfanView reports that your .jpg file is
really a .wmf file with an incorrect extension.
Apps that are not compatible with .wmf files
would not open it.

Thanks... for providing explanation and alerting me to irfanView.
Inasmuch as I found a copy available for download from the PCworld
website, and I trust PCworld not to post applications with hidden
nasties, I plan to try it out.
