Just use a ByteString as your data type! =)

For example:

import Yesod
import Data.ByteString (ByteString)
import Database.Persist.Base
import Database.Persist.TH (share2)
import Database.Persist.GenericSql (mkMigrate)

share2 mkPersist (mkMigrate "migrateAll") [$persist|
    ident String
    password String
    photo ByteString

Hope that helps,
