226561 - Recognizing filetypes of files

Status: RESOLVED INVALID

(SeaMonkey :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Firebird/0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5) Gecko/20031007 Firebird/0.7

It may just be me, and it probably is, but no one has been able to provide me
with a solution. I have this upload forum and then a php line

if (($_FILES['img1'] != "") && ($_FILES['img1']['type'] == "image/pjpeg")) {

which checks whether a real image was sent and whether it is JPG or not. This
worked fine in Internet Explorer but Firebird (and Mozilla) seem to pass another
value for filetype of a JPG file, is this possible? And if yes, which one?

Don't file a bug as a Firebird bug if it occurs in Mozilla as well.

You might try image/jpeg.

Not a mozilla bug...  We recognize the following MIME types for JPEG images (and
your code needs to as well): 

  image/jpg
  image/jpeg
  image/pjpeg

In fact, sending image/pjpeg for a non-progressive JPEG is totally incorrect..

Next time, please use Google ("JPEG image MIME type" gives lots of relevant
results) instead of filing Mozilla bugs on resolving your server configuration
issues...
