Upload and attribute a file (Xpert)
The 'Upload and attribute a file (Xpert)' repository is heavily based on the core 'Upload a file 'repository plugin.
The main difference is that it allows a user to attribute the uploaded image to the copyright holder. This is accomplished by appending the chosen license's icon, the copyright year, URL and author name to the bottom of the image.
The size of the image is determined by a dropdown menu at the upload stage with small, medium (standard) and large options.
The background and text colour of the appended copyright information can be chosen from a predefined list of options.
