This is a problem I have dealt with on a number of occasions.  I have 
some example code at the office that I can post for you, but I do not 
have it right now.  I will try to get to it tomorrow.  Actually, I have 
a program that displays image thumbnails exactly as you describe, but 
alas, I cannot post that.

Question: Are you using an AWT ScrollPane or a Swing JScrollPane?

Here is a brief description of the problem:

When asked for the preferred size of a container, a FlowLayout will 
return a size that assumes its children will be laid out in a single 
row.  This is because there is no mechanism to tell the child the 
maximum width available.

When a ScrollPane or the JViewport of a JScrollPane is laid out, it 
gives the child component any size it desires.  After all, that is what 
the scroller is supposed to do.  So the scroller gives the child 
component exactly the size it asks for, and the child is laid out in a 
single row.
