An important part of the process of digital photography I think is establishing a 'workflow' that works for you (pardon the pun). Workflow may sound like it is something that is the domain solely of professionals, but even if you are amateur maybe only taking a handful of pictures it is, I would assert, very important.
I'm now posting to various different photosites, such as Photo.net, Flickr, Pixola, and various stock agenices. Each require a specific quality of image. Different resoultions, file formats, and maximum file size.
Whilst any photo tool can handle this type of transformation, I was looking for something more streamlined. So I'm currently investigating using ImageMagick
More will be posted on this topic !
An alternative that I was considering pursuing is the use of Python and the Python Imaging Library
