OK, I thought this was your original requirement,
the fact that you are now saying this in not desirable
confused me.

The word 'exploded' also confuses me. What does it mean?

In UI? Do you mean User Interface?
How do I have to interpret this?
Are you showing the images in an AWT or Swing object?

The iText Image object can deal with images in all
kinds of forms, including java.awt.Image and byte[].

In their place in webapps is very vague.
I have no idea what you mean by this.
Are we still talking about undesired jars?

How would they do that? With a FileSelector object?
You are not being clear at all.

I don't think your understanding of class java.io.File is correct.

I think you are basing your conclusion on wrong assumptions.

I agree with Paulo. Your question isn't going anywhere.
You have me all confused; probably because I fail to
what this has to do with iText and because you have
some serious misconceptions about webapps.
