Image metadata is a complex field with multiple standards, the most important among them being Exif, IPTC-IIM and XMP. In this guide I try to find a solution to edit (read, modify, remove) image metadata (jpg, png, …) on Linux, if possible with a graphical user interface (GUI).
Many photo editors and image manipulation programs on Linux are capable to read and display Exif and XMP information. The GIMP can import and export .xmp files, but is unable to edit image metadata on-the-fly. Here is a screenshot of the GIMP's 'Image Properties' dialog:
Photo Editor Linux Photo Software. VeryUtils Easy Photo Editor v.2.3. VeryUtils Easy Photo Editor is the fastest and most fun way to edit your digital photos. Best Photo Editors for Linux. See the list of best photo editing tools for artists and photographers who are interesting in working with Linux. GIMP has been available for Linux for a long time. This multipurpose image editing software is also seen as Photoshop alternative. It offers similar features. It has many options to edit photos. Fotoxx is a free open source Linux program for image editing and collection management. The goal is to meet the needs of serious photographers while remaining fast and easy to use.

Same thing for Eye of Gnome (aka Image Viewer), gThumb and most photo managers on Ubuntu, Linux Mint, Fedora, and most Linux distributions: they all can read at least Exif, but can't edit image metadata.
Currently there are only three pieces of software who are capable of editing pictures metadata. One of them is not Free Software: XnView is an image organizer which has been around for decades and comes as a Freeware for non-commercial use. Free camera viewing software.
Download and install XnView MP from the official website. Open and select (with Control or ⇧ Shift) one or multiple files in XnView's file browser, right-click on them and select 'Edit ITPC/XMP'. You'll get the following dialog, which also allows you to batch edit metadata information.
Saving metadata with XnView works fine, but I couldn't figure out what kind of metadata I was editing. Was it Exif, XMP, or ITPC/IIM? The only solution was to edit and save changes, and later check the metadata information in an image viewer.
Also, adding Creative Commons license link in the Copyright field would create a dc:rights field, which is ok. The Credits and Source fields of the XnView metadata editor create photoshop:Credits and photoshop:Source metadata entries. I found no way to create dc:creator or dc:publisher XMP ITPC entries.
Darktable is not a metadata editor, but an open source photography application and RAW developer. Install Darktable and import a bunch of files (lighttable/import module on the left side). Select one or multiple files and check out the 'metadata editor' in the right sidebar:
Unfortunately, Darktable is only able to edit a very limited set of metadata: title, description, creator, publisher, and rights. Batch edition is possible, though. Don't forget to export through the 'export selected' module. I had some trouble conserving the color space and ended up with considerably bigger image files (working with .png pictures) than the original after adding metadata.
DigiKam is probably the most advanced photo editing software on Linux. It is written in QT for the KDE desktop environment, which is installed by default on Linux distributions as OpenSUSE, Kunbuntu and Mageia.
If you use Ubuntu, Linux Mint, Fedora, Debian with their default desktop environment (Unity, Cinnamon/Mate, Gnome), then installing DigiKam is not especially recommended, as it would come with huge dependencies.
DigiKam's Metadata Editor supports more than a few basic tags: a well-designed dialog makes editing EXIF, IPTC and XMP tags clear and understandable.
If you happen to use KDE as your desktop environment, DigiKam is the best tool to edit image metadata. If you use Ubuntu, Linux Mint or any other distribution with another desktop environment, give XnView a try. Apart of its perfectible metadata editing capabilities, it happens to be a fantastic image manager and viewer.
In both cases, using command line tools may save you some time a the end. There are two GPL-Licensed powerful command line tools on Linux: Exiv2 and ExifTool. https://goosecrets840.weebly.com/wizard-of-oz-online-slots.html. I ended up using ExifTool for my needs:
