Using your standard tool for copying files (e.g. Finder in Mac OS, or Explorer in Windows, or...), put the image file into the GitLab project. You can find the project as a regular folder in your files.

to the repository:
git add NAME-OF-YOUR-IMAGE

git commit -m "DESCRIBE COMMIT IN A FEW WORDS"
Now you can push (send) your changes (in the branch NAME-OF-BRANCH) to GitLab (the git remote named 'origin'):
git push origin NAME-OF-BRANCH
Your image will be added to your branch in your repository in GitLab.
