I did a test on a win box and it reported image/pjpeg
I ran tests on other browsers/platforms, and for a .jpg image, only a handful of win boxes reported the 'pjpeg' thing.
I also did tests using 'regular jpegs' and 'progressive jpegs' and that had no effect.
Apparently the ms browser on a win box calls a 'jpeg a 'pjpeg'
Anyway, to all, thanks for all the help, it's all working now.

I suspect this may be a browser/platform issue. I've recently run some tests and below are the most interesting results (mime types):
IE 6 on PC: something.jpg -> image/pjpeg something.tif (pc format) -> application/octet-stream something.tif (mac format) -> image/tiff
IE 5 on Mac: something.bmp -> application/octet-stream something.jpg -> image/jpeg
NS 4.7 on Mac: something.bmp -> image/x-MS-bmp
Opera 7 on PC: something.bmp -> image/x-windows-bmp
I suspect if you want to validate jpgs, use image/jpeg and image/pjpeg or validate by examining the extention (ie ".jpg"). I don't know how safe the latter is.

Hi All,
I have a system that allows a person to upload photos to the server via an admin web form.
I have been using the code for about a year with no problem. I designed it specifically for a client of mine that has just started cruising on a sailboat for a few years.
They tryed uploading a photo from a public library via the web form and they got the error message that it was not a jpeg file.
The relevent PHP code from my system for the checking is:
if ($type != "image/jpeg") { $ReturnSaying = "!! The file is not a JPEG picture. Please try again"; include("photo_error.php"); exit;
Anyway, this system has been tested and tested again on multiple platforms and conditions, except a public library.
Question: Is it possible that the library is using some proxy system that is messing with the file so it comes out bad?
Also, I have confirmed that the file is a jpeg file.
Any ideas are greatly appreciated, John
