You may have heard of JPEG, GIF, BMP, PNG, and they are all actually different image formats. Each format has its own pros and cons so you will have to choose the correct image format to use depending on the situation. Unless you do a lot of image editing, you probably don’t need to understand what are the differences between different image formats. In computing, JPEG is a commonly used method of lossy compression for digital photography. You may have tons of JPEG photos on our computer because most of the digital camera saves the captured photos in JPEG format. However there are times when JPEG photos can get corrupted or damaged due to many reasons such as bad sectors, partial transfers, blue screens and etc. One easy way you can scan for possible damaged JPEG images on your computer is by using Bad Peggy, created by Coder’s Lagoon the same author who created TruPax.
Bad Peggy is an easy to use program that can scan a defined folder together with subfolders for corrupted JPEG images. All you need to do is run Bad Peggy, click on the File menu and select Scan. Then browse the folder that you want to scan and click the OK button. Bad Peggy will instantly start scanning your hard drive to search for possibly damaged JPEG photos. I tried scanning my hard drive and it found a couple of damaged but still readable JPEG files. It can also tell if the JPEG is a truncated file because the file has not been fully downloaded.

Clicking on the result allows you to preview the found damaged JPEG file and you can move, delete or export the list by right clicking on the file list. Bad Peggy is free and portable that works on both Windows and Linux because it runs on Java.
