Pretty sure only RGB images work on browsers, whereas JPEGs work as CMYK as well... If you can FTP download it AND open it in Photoshop et al, then the issue is the file compatibility with the browser, probably due to CMYK, resolution, or something else.

Re: [PHP] High Resolution Images
Justin,
I did what you said, just uploaded the file and downloaded it again, and
the weirdest thing is happening. When I Form-Upload/FTP-Download it, I can
see it on my local computer, it opens everywhere. Now, when I try to see it
from the web site it is uploaded (http://ebsite/file.jpg), it does not
display. mmm Any suggestions?

Re: [PHP] High Resolution Images
Does the maximum uploaded file size directive in php.ini refuse upload, or
cut the file off at the maximum?
If you're uploading via a browser, it *might* be chopping it off, resulting
in an invalid file.
Try *JUST* uploading the file and saving it to disk, then try downloading &
saving that file to disk... compare file sizes, and try to open the file.
If all this works, then you can rule out a file size issue, and look at
other issues, like a potential bug with large files or large resolutions.

[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)) {
$new_w=69;
$new_h=40;
$t1 = imagesx($src_img);
$t2 = imagesy($src_img);
} else {
$new_w=40;
$new_h=69;
$t1 = imagesy($src_img);
$t2 = imagesx($src_img);
}
header("Content-type: image/jpeg");
$dst_img=imagecreate($new_w,$new_h);
imagecopyresized($dst_img,$src_img,0,0,0,0,$new_w,$new_h,$t1,$t2);
ImageJpeg($dst_img,
"/home/sites/site1/web/uploadedHi-Res/$filename-thumb.jpg", 50);
}
if (($filename_type != "image/jpeg") && ($filename_type != "image/jpg") &&
($filename_type != "image/pjpeg")) {
header("Location:submitError.php"); exit;
} else {
srand((double)microtime()*100);
$randomfile = substr(md5(rand(0,999)), 0, 6);
$upload = "/home/sites/site1/web/uploadedHi-Res";
$upload_path = "$upload/$filename_name";
if (is_uploaded_file($filename)) {
Exec("cp $filename $upload_path");
$link = @mysql_connect(localhost, 'x', '')
or die("Unable to Connect to Database");
mysql_select_db();
$sql = "INSERT INTO VALUES ('$designer_valid', '$filename_name',
NOW(), 'Pending')";
$result = mysql_query($sql) or die("Query Failed");
createThumbnail($upload_path, $filename_name);
header("Location:designSubmitted.php"); exit;
} else {
header("Location:submitError.php"); exit;
}
}
