Some e-discovery cases intrinsically deal with digital image file formats, e.g., workplace pornography and image copyright disputes. But what about cases that, at a glance, don’t involve image files at all? In these cases, is including visual image files in your culling criteria a waste of time and money — or is it due diligence?

There are many cases for which including image files in your culling criteria might seem useless. But consider these relatively common business practices: taking photos of products or product packaging, and uploading them as JPEGs; keeping copies of incoming or outgoing faxes as TIFFs for digital record-keeping purposes; and scanning documents, saving them as non-searchable PDFs, and destroying the originals to save precious filling cabinet space.
