Useful contextual menus for images
There's a boat-load of technologies in OS X that I rarely ever touch beyond the basics and contextual menus are one of those (services would be another; I think that I've never used the Services... menu). However in the past couple of weeks I've found two contextual menus that I really like, both of which operate on images.
The DimensionizerMaybe I'll even get me one of those fancy two-button mice if this contextual menu thing takes off.
The Dimensionizer is a contextual menu plugin for Mac OS X that allows you to discover the dimensions (height and width) of virtually any image with a single click.
Icon2Image is a contextual menu plug-in that you use to convert file, folder and disk icons into images. Any image format supported by your installed version of Quicktime is available for conversion. Standard formats include include JPEG, TIFF, PNG, PICT etc.
