I do not have code available but I can walk you through to process.
To Insert an image into the db, read the file into a byte[].
Create a PreparedStatement with the appropriate SQL.
Call the preparedstatement setBinaryStream(int pos, InputStream is, int length)
Use the ByteArrayInputStream in place of the InputStream as this will take the byte[] in the constructor.
Execute the prepared statement.
To read the image back from the db, run an SQL query and obtain a resultset.
Call the resultset getBinaryStream(int pos) method to get an InputStream.
Use this stream to read the bytes back from the db and re assemble them in an image file.
This method expects to read to and from a file. The ByteArrayInputStream is trick to make the db think it came from a file.
