I've picked up dreamsubmitter over the past few days..
IT FUCKING KICKS ASS!! If you want a program that can not only do gallery submissions but linkdump, linklist even search engine submissions you should be checking dreamsubmitter out.
It's saving me so much time and bringing in some great new traffic sources
Edit: it does have a learning curve, ive only learnt the basics so far.. but video help is available + i believe the support folk are good too..
