| Does adding files to the same directory it's reading from change how the

Not on the first loop - the *.jpg is evaluated before the loop runs.
Next time of course there are more files.

Just type them. You will find an incomplete command (eg just the first
line from the "for" loop above) will get you the shell's "secondary
prompt", indicating more is needed. When you've entered the "done"
it will run.
