Image Renaming Script

This PowerShell script is designed to batch rename .jpg files within a specified folder, applying a sequential naming convention. The script processes all .jpg files in the folder and renames them using an Image_ prefix followed by a three-digit sequence number (e.g., Image_001.jpg). If a file with the new name already exists, the script appends a suffix (_n) to the filename to ensure uniqueness.

Features

• Sequential Renaming: The script renames each .jpg file in the folder with a sequentially numbered name, formatted as Image_001.jpg, Image_002.jpg, etc., ensuring that the sequence number is always three digits.
• Sorted by Last Modified Time: The images are renamed in order of their last modified date and time, with the oldest image being renamed first.
• Conflict Handling: If a file with the intended new name already exists, the script appends a suffix (_1, _2, etc.) to avoid overwriting files.
• User-Friendly: If the -Path parameter is not provided when running the script, it prompts the user to input the folder path.

Usage

1. Specify Folder Path: You can either provide the folder path as a parameter when running the script or allow the script to prompt you for it.
2. Run the Script: The script will rename all .jpg files in the specified folder using the Image_ prefix and sequence numbers.
3. Conflict Resolution: The script checks for existing files with the same name and adds a suffix to prevent overwriting.

Example

To rename files in a folder located at C:\Images, you can run the script as follows:

.\RenameImages.ps1 -Path "C:\Images"

If the -Path parameter is omitted, the script will prompt you to enter the folder path.

Security Settings

To run this script securely, the PowerShell execution policy should be set to AllSigned. This ensures that all scripts and configuration files are signed by a trusted publisher.

How to Check the Current Execution Policy

You can check your current PowerShell execution policy by running the following command in a PowerShell window:

Get-ExecutionPolicy

If it returns something other than AllSigned, you should change it.

How to Set the Execution Policy to AllSigned

To set the execution policy to AllSigned, run the following command in PowerShell:

Set-ExecutionPolicy AllSigned -Scope CurrentUser
