How can I edit or remove one of my artworks?

Browse to your artwork in the gallery. Spot the ‘edit’ link at the end of the information line below the title of your artwork and click it. Now you can modify your artwork item. If you want to remove it scroll down all the way and press ‘unpublish’. Now it is still there but not visible in the gallery. You can now either republish by pressing ‘publish’ (again at the bottom of the page) or delete it using the ‘delete’ button.
