What are the Image Requirements?
Here are images sizes, in pixels, for all images on the site:
- Auction Banner = 980 x 100
- Hero Image (Modern Homepage) = 980 x 275
- Donor/Sponsor Image = 120 x 120
- Item Images = 336 x 255
- Main Image (Classic Homepage) = 200 x 200
- Main Image (Modern Homepage) = 300 x 200
Image files can be in the following formats: .gif, .jpg, or .png.
The recommended resolution is 72 dpi.
For all images, there are no longer maximum file sizes. If the image is larger than 1024 x 1024 pixels, our system will automatically create a new source image that fits within 1024 x 1024 pixel area rather than using the original image. This approach for image sizing, whether auction banner, item images, donor and sponsor images, article images, or coming soon item images, works the same.
What does this mean? If the image uploaded fits within those dimensions, we save and display it exactly as is. For example, if you upload a donor/sponsor image and it is 111 x 94 it will be left the way it is. If one of the dimensions exceeds the limit, we turn the image into a .jpg and resize it so it remains proportional and is as large as possible, and fits within the dimensions limit. This is automatic.
Additional Helpful Information
- If you don't have access to an image-editing program and you are taking photos of items with a digital camera, we recommend changing the settings on the digital camera to the Lowest Quality setting. In most cases, Higher Quality settings will create files that are too large to upload to your auction. Despite the name, the Low Quality setting is perfectly fine for an image intended to be displayed on the web. In fact, this setting is on your camera specifically for creating web and email-ready images.
- Most image-editing programs contain menu options to resize images in two important ways: Resolution and Dimensions
- Resolution: Image Resolution is a broad subject. Resolution describes the amount of detail that an image contains. The term is used in Film, TV, photography and printing among others. As it specifically applies to images on the web, it means how many electronic dots of color on a computer screen does it take to display an image. These dots of color are called pixels (shorthand for "picture elements"). For our purposes, a thorough understanding of resolution is not needed, because for display on the Web, there is only one correct Resolution: 72 pixels per inch. All images that you view on the Web conform to this standard.
- Dimensions: Image Dimensions on a computer screen are simply the width and height of an image measured in numbers of pixels. See the Image Requirements section below for more specifics.
