@shamrock, your code works perfectly the first time, but like the last script i was working with: if executed a second time, i lose files.

@denn, 'this file is already in the format you stated you want.. so why would you want to move it??', well i'll be adding more photos days later to the gallery, and i'd like to just run the command again, and have the filenames follow the ascending order without disturbing the original (already altered) filenames. and i agree, we're going to need to throw some logic in there, but i would still like to ignore the check to see if the file is already in the correct format, because sometimes, i'll be adding files with intigers in them, but they may be the wrong number. for instance, let's say i have 1.jpg - 10.jpg in a directory. then i add some images like 57.jpg and 1152.jpg. since the filename is an intiger, it's fine, right? no. all of them have to be in ascending order, one behind the other. there can't be any gaps in the integers. so to solve this problem i think all we need is a more intelligent sort and it should work no problem. i'll see what i can do with this.

thank you all for your help and guidance!
Code:
ls -1 *.jpg | \
awk -F"." '
{
  if ($0~"^[0-9]+.jpg$")
     i++
  else
     system("mv \""$0"\" "++i"."$NF)
}'
