How old is your Bash? GNU bash, version 4.2.37(2)-release produces

  $ ls 
  R1004.jpg  R1006.jpg  R1008.jpg  R1010.jpg  R1012.jpg
  R1005.jpg  R1007.jpg  R1009.jpg  R1011.jpg  R1013.jpg
  $ ls R{1005..1009}*
  R1005.jpg  R1006.jpg  R1007.jpg  R1008.jpg  R1009.jpg

Read the post again. Your case works because you have exactly the right number of digits.

Missed that. Well, Bash does it intuitively however you like:

  $ echo {8..12}
  8 9 10 11 12
  $echo {08..12}
  08 09 10 11 12
