Hi @jphilip, thanks for posting.
Exif is not available on Plesk/Windows hosting plans.
If you require this, you may want to consider switching to a cPanel plan. Support can help you with switching hosting plans if you are interested.
Too bad; I cannot change to a Linux OS because I have other sites that require ASP.NET.
The reason I was asking is because when you upload pictures from a Wordpress phone app, you need a Wordpress plugin to change the rotation of pictures, which depends on exif information in the phone. Those plugins depend on the exif PHP extension. I would think this is something that would be needed by a lot of people, so it might be worth adding that extension in Windows plans.
The workaround it to manually rotate each picture on the phone before uploading it, but it is a pain.
Unless you know another workaround.
