What type of inline images are extracted as attachments from Rich Text emails?

Inline images extracted as attachments from Rich Text emails are specifically IPicture based OLE (Object Linking and Embedding) embedded images. This technology allows for the inclusion of images within Rich Text format emails, enabling the images to retain their formatting and properties as part of the email's structure. When these emails are processed, the OLE format helps in effectively managing the image's integration within the email, making it possible to extract it as an attachment.

In contrast, formats like JPEG, PNG, and GIF are bitmap or raster image formats that can be embedded in emails but do not support the same OLE functionality. Therefore, while they can appear as inline images, they do not qualify as "extracted as attachments" in the context of Rich Text emails, which specifically refers to the OLE embedded images. This distinction ensures that the correct technology and format are recognized for extraction purposes.
