dBpoweramp Finder Integration
On the right click menu for images dBpoweramp adds Convert with dBpoweramp Image that will invoke Image Converter. Also is the option View & Edit Info with dBpoweramp Image which displays a EXIF tag editor and also image attibutes (color count, resolution, etc).
Sometimes OS X puts these items on the Right click Services menu, if there are too many other items on the right click.
There is also Convert Folder with dBpoweramp Image on the right click of folders, so they can be right clicked and invoke the Batch Converter with all image files in said folder included.
