MGNLIMG-100 introduced a test that accidentally wrote test images in src/test/resources. Those images have been accidentally committed to the Git repository.
A lot of tests have (since forever) written images in the root folder of the project, which isn't great either.
We could configure the project as such

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
          <systemPropertyVariables>
            <imagesOutputDir>${project.build.directory}/test-images</imagesOutputDir>
          </systemPropertyVariables>
        </configuration>
      </plugin>

Tests should ensure this property is set and fail early if it isn't, or fallback on some default. Tests should ensure they don't overwrite the output of another test. A utility method could be provided to return this directory to a test class/method, suffixed with the test name, for example.
