As much as possible, I like to work with files in their simplest formats. So I get curious when agencies send me images that are obviously bitmaps/scans, but they are provided as EPS files.
ie. I don't see any layers or paths.

I usually open them in Photoshop and resave as TIFF, as it has fewer options to go wrong than EPS.

Has something else been done that needs EPS format? I have noticed some of the images scale up much smoother than my TIFF version.

What benefits or situations would there be that I would want to use such an image in EPS?

Thanks
