A user made a great suggestion for an addition to this script.
The free Export Images for Web script (which you can download here) will export any objects that you add to InDesign's Articles panel to JPG and/or PNG format at various resolutions, which you can customize. Many users have told me that they find this script useful.
A recent user pointed out that, since you can't add inline or anchored objects to the Articles panel independently of their parent story, there was no way to output such objects with the script.
Now, in the updated version of the script, you have the option of outputting all inline and anchored objects in the file in addition to objects added to the Article panel.
