The easiest solution might be to use the commercial A Better Finder Rename to achieve this.
For a free alternative, you can install the command-line
You can now use, in the Terminal, either of:
rename -d img_ * rename "s/^img_//" *
to strip away the prefix.
You can use Automator's Rename Finder Items action:
Start Automator, select Workflow, and add Get Specified Finder Items and Rename Finder Items from the library on the left to the workflow area on the right by double-clicking.
Drag and drop the files you want to rename to the list in Get Specified Finder Items.
Change Rename Finder Items to Replace Text as desired, and click the Run button.
Result after execution:
You can easily change this workflow to make it repeatable, e.g. with selected Finder items instead, and save it as Application or Service.

osX has something like this built into finder now.
Select all the files you want renamed
From the right-click menu (or File menu) choose the
Rename # items option
You'll be presented with a dialog window with options, one of which is
Enter your prefix - "img_" in the
Find box and leave the
Replace box empty
If you want an elegant, easy, and feature-rich solution, I personally like Name Mangler.
Used to be called File List and was free, now it costs $10. May be a little steep for some people, but it's well-written and extremely functional if you don't want to get into the command-line methods of doing this.
