-'imv-folder' is a wrapper for 'imv' that auto-selects the folder where the image is located, so that the *next* and *previous* commands function in the same way as other image viewers.
+'imv-dir' is a wrapper for 'imv' that auto-selects the directory where the image is located, so that the *next* and *previous* commands function in the same way as other image viewers.
