We really need a proper photo system for WordPress. All the ones I have tried are missing features, got broken in 1.5, integrate poorly, or just plain don't fit in nicely with the rest of WordPress.
We need a system that is as clean and compact as WordPress itself is; something written from scratch that is designed to be used with WordPress, and not an attempt to merge an existing gallery program.
I might sound a little harsh, and I appreciate a lot of plugin authors have put in a lot of hard work, but there are too many image / gallery plugins for WordPress that don't make much sense at all.
It'd be fantastic if the WordPress team could come up with an official solution; there are so many people including myself who want a nice way of putting photos on their WordPress-powered sites.
Personally, I'd want to put images in my posts as thumbnails, while having them organised in a browsable gallery at the same time, i.e., you have a set of little thumbnails in your post that you could click on, then be taken to a full size version. And I'd want those friendly URLs to be applied aswell. For instance, "/images/albumname/imagename".
You could also have a tab on the admin panel to organise your albums and images.
Something properly integrated like this would be truly awesome. How about it, guys? I've been waiting for something like this for ages. I know it'd be a huge task - but please consider it, if you're reading.
