When I select and image via upload OR browse on server, it doesn't display on the item page nor do I see a preview on the image tab for that item as I would when selecting a category image. Since I can see it in the category image tab, I am lost as to what the cause of the problem is. My permissions are all 777 on the test server.

Another note.. when I upload an image on the category options, it displays fine. When I upload an image on the item options, it goes through the motions of uploading and when its done and the page refreshes, it is the way it was when I first loaded it. No image preview and on the front end, no image.

Ideas anybody?

I have had the same problem when trying to upload large images. Try using a small jpg, one just larger than the large size that is going to be created by k2. Also keep the filename simple and consistant "filename.jpg"

Hi William. I did try using a test .jpg file with a simple name (robodog.jpg) that was less than 20KB in size with the same result. It's so weird. Works great when I add an image to a category, but on an item it fails.It simply uploads the image (or so it seems) and then returns me back to the main screen for editing that item and when I go to the image tab. nothing (see screencap below). If I view the actual item's page, only text. no image.

I AM using the K2Profiler template form K2Joom, but this shouldn't affect anything. It's a very perplexing puzzle.

I just wanted to post that user Nick Texidor solved this issue for anyone else having this problem. Solution is below;

For those people having problems with the uploading of files, and have already ruled out a problem with permissions, I have a solution....

The quick fix is to edit /administrator/components/com_k2/lib/class.upload.php. Go to the init() function, and change the following variables from true to false:

$this->mime_fileinfo = false; // MIME detection with Fileinfo PECL extension
$this->mime_file = false; // MIME detection with UNIX file() command
$this->mime_magic = false; // MIME detection with mime_magic (mime_content_type())

You are 'SUPPOSED' to be able to override these settings in the calling script, however, because of a fundamental flaw in the design, it doesn't actually work :^)

I have seen that post, but i dont understand why I have not had this problem on many sites on my dedicated server. Could it be server/hosting settings causing some to get this error?
