As you can see I cannot rotate an image that I uploaded in a discussion. How is this done?
I did try to look in knowledgebase for an answer here, to no avail: https://support.socialengine.com/php/customer/en/portal/articles/1650798-admin-panel---layout->-file-media-manager?b_id=14386
Is that image from a cell phone? Do you have Imagick (Image Magic) on your server as recommended? I am not sure Imagick will help but it does help with some photo issues. If the image is from a mobile device, those can be saved with different coding and may cause issues but I would need to test on mine to see.
I tested on my test site using an image from my cell phone which I had sent to my mac as I can't add it via phone to the forum area. It seems to load in the correct orientation. Please don't take offense to the image of my cat below. It's one of my faves.
