For your auction images, it is important to use good quality photos. Make sure the image is square and at least 600 pixels on a side. If you are not comfortable editing images yourself, you can always hire an image editor. Adobe Photoshop, for example, can be helpful. However, you should ensure that your auction image has a good aspect ratio of 1:1 and is optimized for web use.
A good auction image will attract the attention of potential bidders and help them make a decision. It should be clear and readable with no visible flaws. It should also be well-lit with no shadows or glare. In addition to that, the background of the photo should be simple. A cluttered background can distract the viewer’s eye and cause confusion about the items for sale
