[Urgent] Converting an Non-JPEG Image to JPEG

[Ming]

Hi All,

I want to write a PHP webpage which allows people to upload images (no
matter what formats) to me and at the same time converts any non-jpeg
image to JPEG.

Here's what I have:

$FileDest = "/uploads/1.gif";
if (!move_uploaded_file($_FILES["file"]["tmp_name"], $FileDest)):
$Error = "Yes";
endif; // This will upload an image to /uploads/1.gif

$V2_MagickCommand = "mogrify -format JPEG ".$FileDest;
exec($V2_MagickCommand); // I tried to use this to convert the image's
format (gif) to JPEG but this doesn't work.

$FileDest2 = "/uploads/1.jpeg";
$V2_MagickCommand2 = "convert ".$FileDest." ".$FileDest2;
exec($V2_MagickCommand2); // I also tried to use this to convert the
image's format (gif) to JPEG but this doesn't work, either.

What seems to be wrong? How do I modify my codes to make my uploading
webpage to work?

Any idea is appreciated!

Some ideas I can think of:

1) You check whether file was uploaded successfully. Then you proceed in
either case.

2) You process all files, even JPEG or Excel ones. You should check
$_FILES['file']['type']

3) Print the command line passed to mogrify to see what it looks like, just
to make sure there aren't simple syntax typos.

Some Explanation:

When I tried to convert an image to JPEG (for example, pic.gif to
pic.jpeg), I would get pic.jpeg.0, pic.jpeg.1, pic.jpeg.2, pic.jpeg.3,
pic.jpeg.4, pic.jpeg.5 instead of simply "pic.jpeg".

I don't know why. Any help?

Was it an animated GIF? could those be each frame of the animation?

Use Image Magick from the command line to first be sure that it is
working as expected. Once that is figured out, then start putting pieces
in your PHP script.
