Hey Toni. If you upload an image and insert it as full-sized and not a thumbnail then the metadata will display underneath. However this will only work if your original images includes the metadata in the first place.
I've created a separate post on how this works here:
If you upload an image to one of the forums and this includes EXIF data then the following EXIF fields will be displayed underneath your image: Camera Lens Focal Length Aperture Shutter Speed ISO If you don't wish to display this then you can uncheck the box "Show image attachments EXIF data"...
