I think you're best off just reloading the listbox from the directory listing instead of trying to micromanage the old listbox string. Regardless, I don't see where you're restoring any items to the listbox. You delete an item(s) but never stick any back it, at least not in the code you showed.


sir i need to restore all deleted images... not the last deleted image alone.... whatever image i delete i shud be able to restore it sir....

That's fine, but you need to decide how you want to store the content of the "deleted" images. I am assuming, of course, that the images contain indecency so you cannot use the usual trick of uploading them as a youtube video.

I don't know what restore means either. Have you seen this in the help:

By default, the delete function permanently deletes files. To move them to a different location instead, use the Deleting files preference:
On the Home tab, in the Environment section, click Preferences > General.
Set the Deleting files option you want.
Setting the preference to delete files permanently makes delete run faster.
To override the preference when using the delete function, use the recycle function.

So if you want to restore a function, you'll most likely need the movefile() function to restore it out of the recycle bin, but you'll first need to use the recycle() function rather than the delete() function.
