If you have 3rd party image extensions installed (EG imageinfo, FuzzyOCR)
then the image content -is- searchable and a valid part of spam filtering.

Given the processing demands of those modules you care very much about
the size of images attached to messages. With modern 10Megapixel cameras
it's not unusual to find 2~4Mbyte pictures attached to messages.
