What is it you want to do?
iPhoto is an application - it can not be on a memory stick - it must be in the Applicatiosn folder on your main drive
the iPhoto library is a database - it must be on a volume formatted Mac OS extended (journaled) - if you have any volume with that formatthat is large enough to hold your library (including a memory stick) then simply drag the iPhoto library to it
You can put photos form iPhoto on a mamory stick by selecting them, in iPhoto, exporting (file menu ==> export) to a desktop folder, mounting the MS and dragging the folder to it
