Upload multiple images, store img paths & info to db

[eluser]Vasi[/eluser]
Thanks a lot Narkboy, but here is the thing I can't seem to solve:

In my controller I a have this two functions: insert_to_db() and do_upload() - the catch is I need to insert into the database path of the image which is in the do_upload() function, how can I pass variables through the functions which are in the same controller?
