I have pictures and graphics disorganised in various directories, with names that give no clue as to their subject or theme. eg. img_12345.jpg
I am looking for a software which will find all images and allow me to
1. use the arrow keys to scroll to the next image without having to navigate folders
2. by pressing an F key will allow me to tag the file and save it
quick access, and quick tagging
I tried gthumb and shotwell, but these seem clumsy and time consuming.
professionals, please advise
thank you in advance
