Here you are mixing several things:
- You either run a loop where $N takes values between 57 and 87, and 
then the file name is represented by p00$N.png,
- or you use one command line where curl fetches several files at once, 
and then the file name is represented by p[0057-0087].png (I didn't know 
curl could do this)

If you do both at the same time, you fetch all files 31 times, which 
gives the desired result, too, but will take a little longer :-)

You must have copied something else, perhaps no newline before "do"? In 
your previous try with wget, bash did not complain about "do". It ran 
the loop and gave you dutifully 31 time "wget: command not found".
