Unable to Add Image to Document Using DocX4J

Question

I'm trying to add Image to Document (.docx) using Docx4j library with code like below. The image already exists in local machine and initially i taught it doesn't support png and then i have renamed the image to jpg and it still throws error

String userSignatureFile = "C:\\esignature\\sign.jpg";

            // read the signature image into Bytes

            InputStream inputStream = new java.io.FileInputStream(userSignatureFile);
            long fileLength = userSignatureFile.length();    

            byte[] bytes = new byte[(int)fileLength];

            int offset = 0;
            int numRead = 0;

            while(offset < bytes.length
                   && (numRead = inputStream.read(bytes, offset, bytes.length-offset)) >= 0) {
                offset += numRead;
            }

            inputStream.close();

            String filenameHint = null;
            String altText = null;

            int id1 = 0;
            int id2 = 1;

            // create Inline Image

            BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordPackage, bytes);
            Inline inline = imagePart.createImageInline( filenameHint, altText, id1, id2);

            // Create Drawing and add to Run
              Drawing imageDrawing = factory.createDrawing();
               imageDrawing.getAnchorOrInline().add(inline);
            // add Text to Run
            run.getContent().add(imageDrawing);

            // add Run to Paragraph
            ((P) jaxbNode).getContent().add(run);

And below is the error message

If the PNG format is not supported, then *renaming* won't help – changing the filename doesn't change the data within the file! — lenz, Jun 14 '15 at 21:13
Even i have created new jpg and still it doesn't support and gives error as org.docx4j.openpackaging.parts.WordprocessingML.BinaryPartAbstractImage.ensureFormatIsSupported(BinaryPartAbstractImage.java:429) — JavaGeek, Jun 14 '15 at 21:19
Apparently the file cannot be found. Are you sure the path is correct? — lenz, Jun 14 '15 at 21:40

Actually its my mistake where i used input stream and directly passed the file path string (without File ) and after correcting as below, it worked.

Correct

File file = new File(userSignatureFile);

            // read the signature image into Bytes

            InputStream inputStream = new java.io.FileInputStream(file);

Wrong

        InputStream inputStream = new java.io.FileInputStream(userSignatureFile);
