Created attachment 39580 [details] original sample file I tried to change the document's Author with setAuthor(), then i figured even if i just called getSummaryInformation() and save the file, document's images are corrupted and seen as "Read Error" My test code is: POIFSFileSystem originalFile = new File(file); HWPFDocument doc = new HWPFDocument(originalFile); SummaryInformation summaryInfo = doc.getSummaryInformation(); FileOutputStream outputStream = new FileOutputStream(tmpFile); doc.write(outputStream); outputStream.close(); doc.close(); Is problem is specific to document or POI can't process file correctly?
