If you have cooked the fish, a good technique is to eat one, drop one, eat one, drop one, rinse, repeat.
Giving such stuff away (fish, minerals if you want to power-mine, etc.) is the fastest, but you won't always find somebody willing to take it.
I'm not quite sure the is a "quick" way to drop anything on runescape besides having a fast finger lol. But when banking there is a quick empty button located in the bottom left of the the bank.
Auto bank as in bot? If so....it already does bank for you, unless you program it not to...example: program it to drop mine instead of banking. hope that helped.
The most expensive drop you can get on runescape is the corrupt dragon battleaxe at 3.9m
you can get an easy one at Draynor Runecrafting Guild for a small price.
