The new Photobucket is still below par (April 3rd) because among other things there's a silly 1024-pixel width limit on images, meaning if you post any pic bigger than that in a forum, PB auto-shrinks it to 1024, what a cheek!
Imageshack is better (but not perfect) so I'm sticking with Imageshack because it gets the job done fairly well enough.
Incidentally, although you can sign up for FREE Imageshack i wouldn't recommend it because the free version has a "downtime" restriction which means your pics randomly won't display in forums for a brief period each month (i.e. replaced by the dreaded red 'x') whereas a paid subscription virtually eliminates downtime. I took out a 1-year 22 GBP/34 USD sub.
But like people have said, there are plenty of other image hosts around besides IShack and Pbucket so shop around to find one you're comfortable with.
EDIT- it seems Pbucket has fixed the 1024-wide limit so that's something, but there are still a few bugs and glitches need fixing, so I'd still rate Imageshack as better.
