for file in *.jpg; do convert $file -resize 1000 resized-$file; done

Choose an image with some text written to start detection.

It shows up one image every 5 seconds (one per post). You can go forward and backward using cursor arrows (click inside first to be in context).

You could extend this example adding up and down cursor arrows to switch between different tumblrs.
