This may sound silly, but you are uploading in binary mode right?

Subject: [PHP] High Resolution Images
> Hello,
>
> I am creating a script that takes an uploaded image, creates a thumbnail
> from it, and saves both files.
>
> The script works great, but the problem is, the files It will have to
> handle, are high-resolution files (300dpi, 24 bit-depth).. it works fine
on
> regular files (72 dpi), but when I upload a 300dpi image, it says that the
> image is not a valid JPEG file.
>
> Warning: imagecreatefromjpeg:
> '/home/sites/site1/web/uploadedHi-Res/mo_0001.jpg' is not a valid JPEG
file
> in /home/sites/site1/web/site/designers/doSubmit.php on line 6
>
> The image appears to be valid here, it opens on photoshop, and everywhere,
> however, once uploaded, the image seems to be corrupted somehow, bc if I
> download it again, it won¨t open anywhere. Has this happened to anyone
else
> on this list?.. if so, please advise!.

> Here is the code for the script if it helps:

> function createThumbnail($path, $filename) {
> $src_img=ImageCreateFromJpeg($path); //HERE IT SAYS IMAGE NOT VALID
> if (imagesx($src_img) > imagesy($src_img)) {
