8. Why am I getting an "Invalid Image" message, when I am selecting a JPEG file for repair?

An image file is made up of two parts namely the file container and image data. The container is the common structure that uniquely defines the JPEG image. If the container of a JPEG file is damaged or corrupt, then Stellar Repair for Photo will be unable to identify the file as a JPEG file, and you will receive an "Invalid image" message. Such images are corrupt beyond repair that indicates such JPEG images are severely corrupted and it is impossible to repair them.

The images that have thumbnails will be listed along with all its thumbnails. The thumbnail images will be named as IMAGE_NAME_T1.jpg and so on. T1, T2 is the name of the thumbnail of the same image. If an image has four thumbnails, it will be listed as IMAGE_NAME.jpg, IMAGE_NAME_T1.jpg, IMAGE_NAME_T2.jpg, IMAGE_NAME_T3.jpg, and IMAGE_NAME_T4.jpg.

10. Why are some JPEG files not completely repaired?

An image file is made up of two parts namely the file container and image data. The container is the common structure that uniquely defines the JPEG image. If the container of a JPEG file is damaged or corrupt, then Stellar Repair for Photo will be unable to identify the file as a JPEG file, and you will get an "Invalid image" message. In case, the container of a JPEG file is intact, but its image data is corrupt even then Stellar Repair for Photo will be able to repair the image. Such a repaired image will have defects like loss of color, or a part of the image will be missing. These defects are due to image data being corrupt.

In such situations, there is an advice that you try and extract the thumbnail of the image (if any).
