As I don't have a sample document to test on, I can't guarantee this would work but conceptually, this code will find graphics from the current selection forward and if the found graphic is marked as a tracked revision it rejects the change and searches for the next graphic.
Code:
Sub Huh()
Dim aRng As Range
Set aRng = Selection.Range
aRng.End = ActiveDocument.Range.End
With aRng.Find
.ClearFormatting
.Replacement.ClearFormatting
.Text = "^g"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindStop
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
Do While .Execute = True
If aRng.Revisions.Count > 0 Then
aRng.Revisions.RejectAll
End If
aRng.Collapse Direction:=wdCollapseEnd
aRng.End = ActiveDocument.Range.End
Loop
End With
End Sub
