loading images

We're not going anywhere like this. You can use Image.getInstance(byte[]) 
where byte[] contains the image. Load your image to a byte array using 
whatever ways Java provides you. Note that iText has nothing to do with it. 
If you can't do that, then ask your question in a Java forum as it has 
nothing to do with iText.
