How can I upload this type of image to gallery?? the uploader does not seem to support this format. Although I added this format type to config.php, it can be added, but the images cannot be shown. How can I solve it?

And If I uploaded JPEG files, it does not allow me to upload excess 2mb. I already extend the limit to 50mb in plupload > upload.php. Any suggestions for this??

it can be added, but the images cannot be shown.

PHP GD Library, working behind KCFInder, does not consider TIFF an image type. That is the reason why we don't get its thumbnails.

As for the error message seen in the image (POST size exceeded), that seems to be a problem with your PHP configuration. I think you need to take a look at your server's php.ini settings.

But I can uploaded the images that >2mb by using bulk uploader, it only limited to 2mb size when I used KCFInder.
