5 thoughts on “How to edit image metadata on Linux using a graphical user interface”
fotoxx lets you change Metadata info, and choose your current image’s Caption and Comment as well as view images in directories with filename and some other Metadata as labels. You can set up trees of tags with Categories and put those in at the same time, to use for sorting the images into “album” groups for moving or copying out. The code is gtk and perl with many filetype handlers. Your labeling is stored in plain text files, easy to copy out into documents, transfer, edit, etc.
You should give some additional details, some tools write directly into the image file, others don’t. For example darktable does not change the original image, it writes into a sidecar file (.XMP).

I don’t know whether you actually tested Gthumb or not, but your statement that it is only capable of reading meta tags, couldn’t be further from the truth. And it seems to do a fairly good while it is at it!
All one have do is to press the ‘T’ key – either under the Thumbnail view or the “larger” view – and voilá: it reads any existing tags already embedded in the selected file. Next, you have to keep typing any new ones (just don’t forget to confirm, via the pull down list, to actually create any new tags) and you’re done.
I would also suggest that MaPiVi is an excellent program which needs to be on this list. It’s capable of editing and bulk-editing many kinds of image metadata, including IPTC Keywords (which is why I got it). It’s written in Perl/TK so it’s cross-platform. A somewhat old version of it is included in the Ubuntu Linux distribution.
One of the main drawbacks of MaPiVi is that it won’t handle the metadata in Nikon .NEF (raw) format files, which is pretty much the same as that in other formats such as JPEG.
