Pilot Custom Inlaid nib falls off.

[PecosPeet]

My Pilot Custom Black Stripe's inlaid nib likes to fall off whenever I clean the nib.

That was not too bad as I just put it back on. But lately, ink has started to leak and blob from the edges of the inlaid portion (there's a little peeking out in the photo below). So, I am figuring that the nib is held in place by more than the clips on the nib - I'm guessing there is some kind of glue involved.

What is a good way to repair this so the nib stays where it is supposed to be?

And on another topic, how do I resize the images? I searched all over and can't find anything to adjust them. (EDIT - I managed to adjust them smaller - thanks to Jar)
