I am trying to take a user uploaded jpeg, convert it to a progressive jpg, and then upload it to my CDN (Cloudinary) in PHP.

I currently have the following code: 

$data = file_get_contents($_FILES["file"]["tmp_name"]);
$img = imagecreatefromstring($data);
$prog = imageinterlace($img, 1);

$picinfo = \Cloudinary\Uploader::upload($prog);

I'm getting error, I think because $prog isn't a file anymore, but a created image. Is there any way to make the created image have a file path temporarily so it could be uploaded? How should I go about trying this?

  • why don't you use an image manipulation plugin like phpthumb, however make sure that it is possible to convert to progressive using this plugin. Do some research and I am sure you will find the right one. – insanityCode Oct 15 '13 at 06:05

Figured it out. Turns out Cloudinary has a built in function for progressive jpg conversions!
