string = "rose.jpg"

=> "rose.jpg"

modified = string[0..-5] + "_big" + string[-4..-1]

=> "rose_big.jpg"

you might wannt to check for the "." in that string and cut it there. check out some ruby basics for string manipulation.

Hi, here’s another option using the File class:

filename = File.basename( filename, “.jpg” ) + "_what_ever_you_want + File.basename( filename )

Good luck,
