I'm curious what thumbnails best practices people have come up with. For me, with timthumb and other solutions, thumbnails have been a pretty big annoyance and waste of time. What I'd like to do is create one thumbnail repository.
I'd also like to be able to tell clients: when you find a decent image for a thumbnail or for a post, upload it HERE. It doesn't matter if its on S3 or my server or whatever, just so that I can have them upload images, so I can browse them, so the client can select them easily for posts, and so that they are displayed quickly, easily and well in themes.
Regarding size, well, 150x150 isn't big enough for certain themes. Then what about sliders?
Is there a way to just upload the photo, and have a cropping tool that either allows you to reduce the size of the photo or allows you to cut a section of it out for display as a thumbnail?
Anyway, I am looking to create thumbnail best practices, so let me know how ya'll are handling things.
