anyone here tonight? Need jpgs, please

[Barbara Brundage]

Hi, anyone who is here tonight. I am helping to test for a problem with mail attachments that may be caused by EXIF data in jpgs. But since I don't shoot digital I don't have any pix with EXIF data to use for testing. Can somebody send me a jpg or two that still has EXIF data in it, please?

I may be a day late and a dollar short here, but I've had a look at the
"innards" of a jpeg that contains EXIF data from my digital camera, and
I think I've figured out where a possible e-mail attachment headache may
occur.


A "normal" jpeg contains the tag "JFIF" in bytes 7, 8, 9 and 10 of the
file while the jpeg from my camera has the tag "Exif" in the same
position. The "Exif" file also contains a lot more readable text at the
start of the file than does the standard "JFIF" type file.

Because "Exif" is not a recognized MIME type and the extensive text at
the start of the file, e-mail tools don't necessarily recognize the
picture as being a binary file and don't encode it properly for sending,
thus "bending, folding, mutilating and stapling" the result.

The only, reasonably sure, way of getting around this is to archive the
file using something like Stuffit, PKZip or WinZip. This will encase
the image in something the e-mail tool recognizes as being binary and
the result will be properly encoded for transmission. If you're not
sure what platform the recipient(s) are using, then I would suggest
using "zip" format, as I haven't met a platform yet that can't handle
it. Not all MS-Windows or *nix users can handle a native Stuffit file.

If you still need examples of files with Exif data, contact me directly
or leave a note here in the newsgroup and I'll zip some up and send them
to you.
