Resize Image Nautilus Script is a Bash script extending Nautilus, the GNOME file manager, to easily resize images using ImageMagick, e.g. to create files suitable for sending by email. The script resizes selected files to the given pixel width/height and saves them with the same file name in a new sub folder (e.g. "1024px"). Existing files in the resize target sub-folder will not be overwritten. Different sizes can be directly chosen in the Scripts sub-menu of a file's context menu.
Masna provides a simple graphical interface (GUI) to manage Nautilus scripts. For scripts that are part of the system-wide Nautilus script collection (by default /usr/share/nautilus-scripts; you can change this in the settings dialog of Masna), it manages symlinks in the user’s Nautilus script folder. For scripts in the user’s Nautilus script folder, it manages the file permissions.
