Email Logos and Other Small Images

Email Logos and Small Images

This technical note explains how automated file processing will convert small images during ingestion in the Lexbe eDiscovery Platform (LEP).


The inclusion of logo files or other small images (e.g. JPEGs, PNGs, HTML, etc.) as part of a production is common practice in the eDiscovery industry and among vendors. Additionally, it is considered a best practice to produce email families in their entirety when at all possible.

Deleting Logos and Other Small Images

There is no automated way to determine if an email attachment is a substantive attachment or non-substantive logo. Additionally, if incomplete email families are produced (e.g. an email is missing an attachment), it can raise questions during review and will often result in a request that the missing attachments be produced. As such, the deletion of logos and/or other small images is not a best practice and should be avoided unless jointly stipulated to and memorialized in an ESI agreement or court order.

Furthermore, LEP is purposely designed to prevent the production of an incomplete email family. As such, LEP codes documents consistently to ensure that when an email body or attachment is coded as Responsive, Privileged or Work-Product, the entire family is coded in that manner as well. For example, if an email is coded as Responsive and some of its attachments Privileged, then, at the time of production, the production validation feature will detect coding inconsistencies and give the option to expand the Responsive and Privileged coding to the entire email family.

If you have a document that is responsive, but only partially privileged, then please visit Partially Privileged Emails for more information.

Identifying Email Logos and Small Images When Receiving a Production


Run the deduplication feature to detect duplicates of email logos and repetitive small images (see Deduplication for more information). Once deduplication has been run, follow the steps below using filters to further cull and identify these types of images.


First, open the Browse tab, go to Fields->Show Fields, and select the following data fields: Extension, Pages, Word, Size, IsAttachment, and IsDuplicate.

In the Browse tab, go to Filters->Select Filters, and then begin filtering by common file extensions (e.g. GIF, PNG, etc.). You may review these filtered documents using the Doc Viewer, or, alternatively, you may create a custom field and tag your results, so you can review at a later time.
