jpeg lib also working properly with this image.
Please see this code (from jpeg-6b):
next_marker (j_decompress_ptr cinfo)
{
int c;
INPUT_VARS(cinfo);
for (;;) {
INPUT_BYTE(cinfo, c, return FALSE);
/* Skip any non-FF bytes.
* This may look a bit inefficient, but it will not occur in a
valid file.
* We sync after each discarded byte so that a suspending data
source
* can discard the byte from its buffer.
*/
while (c != 0xFF) {
cinfo->marker->discarded_bytes++;
INPUT_SYNC(cinfo);
INPUT_BYTE(cinfo, c, return FALSE);
}
/* This loop swallows any duplicate FF bytes. Extra FFs are legal
as
* pad bytes, so don't count them in discarded_bytes. We assume
there
* will not be so many consecutive FF bytes as to overflow a
suspending
* data source's input buffer.
*/
do {
INPUT_BYTE(cinfo, c, return FALSE);
} while (c == 0xFF);
if (c != 0)
break; /* found a valid marker, exit loop */
/* Reach here if we found a stuffed-zero data sequence (FF/00).
* Discard it and loop back to try again.
*/
cinfo->marker->discarded_bytes += 2;
INPUT_SYNC(cinfo);
}
if (cinfo->marker->discarded_bytes != 0) {
WARNMS2(cinfo, JWRN_EXTRANEOUS_DATA,
cinfo->marker->discarded_bytes, c);
cinfo->marker->discarded_bytes = 0;
}
cinfo->unread_marker = c;
INPUT_SYNC(cinfo);
return TRUE;
}

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.

Interesting. Could you try to open the file with the exif functions?
But however the file is borked.

Description:
------------
getimagesize fail with jpeg created by 602PC Suite software
Example jpeg:
http://si.infonet.ee/wrong_jpeg.jpg
All other software (Photoshop, ACDSee, xnview, IE, Mozila, Opera, etc)
open this file correctly.
ImageMagic/identify says:
/usr/local/ImageMagick/bin/identify: Corrupt JPEG data: 2 extraneous
bytes before marker 0xfe
After some debuging, i can see, than this jpg file have 2 zero byte
before next marker, and php_next_marker fail with this data.
