The version of GIMP I am using is 2.10.22. I used "image properties" to add a comment (caption) to my photos. I closed and saved the image. Next, I edited the metadata, then exported the XCF image to JPG. After exporting the photo, I get a pop-up showing a preview of the metadata and comments, so I clicked "export" again.
On my desktop, I go into my folders and open the exported JPG image. All I see is the image itself with no comments or metadata. Is that supposed to happen?
My professor has a program where she can see any photo added in with a caption. I've submitted all 3 of my JPG photos (exported from GIMP). So.. my question is: Will she be able to see all 3 captions and metadata from those photos? Or will she see JUST the photos?
It's my first time using this program..so I hope I did everything correctly.
My goal is to have her see everything. I'm on thin ice as of now..

You have not said which version of Gimp you are using but in my version (2.10.18) I can open an image and view the metadata by choosing menu option Image -> Metadata -> View Metadata so use that function to see what metadata your exported image has.
And when you export to JPG there are options on the export window Save Exif data / Save XMP data / Save IPTC data if you don't want any metadata in the exported image then un-check those boxes.
The default image viewer of Ubuntu 20.04 lets you see the meta data of images by clicing the three-lined button (top right corner), choosing Image Properties, and choosing the Metadata tab. Hope it helps.
There are two different things:
the JPEG comment. This is part of the JPEG standard itself, independently of the EXIF metadata. On Linux, the
filecommand displays it. In Gimp , this is the "Comment" inImage>Properties, and also the comment that you can enter in the JPEG export dialog.The EXIF/IPTC metadata: the EXIF-standard medata, which is Gimp is in the
Image>Metadatadialog.
So after filling these two dialogs with this:
You can check the result
