Photo import & image checks

Photos by the hundred, without clicking lot by lot

Photography is often done in batches, by a photographer or a studio, long after the lots were described. The bulk upload takes a folder of files and attaches each one to the right lot by its name. Drop the files, choose the scan type, and Selloff reads the reference at the start of each file name, ignoring what follows a dash, an underscore or "ex". Files can also be matched by lot number within a sale, or by consignor reference within a receipt, which is handy when the photographer works from the catalogue or from the consignor's list.

Options let you set the image as the main one, replace the existing images or mark it for the catalogue, which is accepted only from 300 DPI. JPEG and PNG images are supported, as well as PDF documents. Selloff keeps the original and creates medium and thumbnail versions for screens and the website.

Scan types and validation

Scan types are yours to define: catalogue photos, additional views, certificates, condition reports. A scan type can be private, so it never appears online, and each lot states which scan types it requires. Scan types can require double validation: images then go through a queue where they are validated, refused with a reason or reassigned to another lot, and uploaders see their refusals in their own list.

Know what is missing

The scan check gives, for a sale or catalogue, the coverage of each scan type against the lots that require it, with filters on packaging, image size and minimum estimate, and a table of lots with their image counts and main image. It turns "are we ready for the catalogue?" into a list of lots to photograph.

When one image serves several lots, copy the scans from one lot to another instead of uploading them again. See PDF catalogue generation for how catalogue images are laid out.
