I just checked my Squeak3.8-6665full.image, "right out of the box". 
86301 instances of ByteString. So probably 86% of your ByteStrings are
there for good reasons. (Nearly everything that used to be a String is
now a ByteString, so it's a popular class.)

But it only takes one large instance to make a large image. This code,
to be executed in a Workspace, should give you your top culprits.

	tops := SortedCollection sortBlock: [:a :b | a size > b size].
	thresh := 10000.
	ByteString allInstancesDo: [:s |
		s size > thresh ifTrue: [
			tops add: s.
			[tops size > 10] whileTrue: [
				thresh := tops last size.
				tops remove: tops last. ]]].
	tops asArray inspect.
