Doing a search for:
resize images site:raspberrypi.org yields more about IMAGE size rather than picture.
Likewise with picture resizing.
Like most people I have a digital camera.
When I need to send pictures to someone else - only for reference purposes - it is pointless and somewhat wasteful sending a 5 meg file.
How can I size reduce picture on a Pi?
Short of loading each in a viewer and screen grabbing, I can't work out how to do it.
Please, someone.
