Requirements for Uploading Photos

Great photos are just as important as product descriptions. One bad photo could be the difference in getting that high bid! We allow up to 20 photos per lot.

Photo Requirements

Single Image & Batch/Bulk Image processor
We recommend using images that do not exceed an image resolution size of 3840x3840 (4K). Using the original image size enables bidders to use the Zoom feature. The file size must not be less than 15kb (kilobyte). We accept images in the following formats:

  • .jpg
  • .jpeg
  • .png
  • .tiff
  • .pdf (only the first page)
  • .helf
  • .heic

NOTE: Images cannot contain any URLs, email addresses, contact information or watermarks of any kind

Naming your Photos

Name your photo so it matches up with the lot number it represents. If you have three images for Lot 1, name them like this:
Please remember to always include the “_” as well as the “.jpg”

Similarly, if you have an A lot in your sale (i.e., lot 53A), name the images like this:

Please note, we also accept the following file naming conventions:

1-1.jpg, 1-2.jpg, ... 1-20.jpg
1a.1.jpg, 1a.2.jpg ... 1a.20.jpg

Don’t want to rename your photos?

If you prefer not to rename your photos, you can provide them in the text file under the ImageFile columns within your catalog spreadsheet. Using the columns named 'Image File.1' (ImageFile.1 to ImageFile.20)

Image file columns are only required if the photographs are not named according to lot numbers. You can have up to 20 image file columns.

If using these columns: 

  1. You must list the full image file name including the .jpg extension. 
  2. The image itself must also be a .jpg, .jpeg, .png. .tiff, .pdf (only the first page), .webp, or .heif/.heic.
  3. The file names are case sensitive

Example: If your image is “warhol19front” for lot number 24, then the ImageFile.1 for lot 24 would read “warhol19front.jpg”. 

Additionally, if your images are hosted on a website, you may enter the URL location of your images in the Image File Columns for our image processor to retrieve.
