To upload an advert you will need an image. Image optimal size is 950 px wide x 800 px high (or similar 19:16 ratio). Please ensure your image is a small file size, preferably no larger than 100kb.
Keep in mind your image is your advert, let people know your message very briefly and your Title is your attention grabber. Make it good for people to want to open your advert and contact or buy from you!
