The next few fields are for you to submit photographs of your work. Remember this form is for one work only. You can submit only one photo or many photos of that one work. Ideally they will be suitable for Facebook and website use - if they are then your work will show in these places sooner. The more the better - edge views and detail shots are good. In-situ shots are good too if you can provide.
Please name the files with at least the painting title in it somewhere. Calling the image 20190811_154642-1.jpeg is not helpful
