Like this?

   def pictureMethod
     array = []
     system("ls | grep \"jpg\" > pictures.txt")
     pictureFile = open("pictures.txt","r")
     while (line = pictureFile.gets)
       array.push(line)
     end
     array
   end

Or even

   def pictureMethod
     system("ls | grep \"jpg\" > pictures.txt")
     File.readlines("pictures.txt")
   end

If you don't need to leave the file

   def pictureMethod
     open("|ls | grep \"jpg\"").readlines
   end

|I don't know the Ruby syntax that's why I wrote it in kind of "spoken code":-)

It was close.
