Not at all. The files contain an embedded thumbnail, which, unsurprisingly, is at the beginning of the file. Thus, if the end of the file is missing or corrupt, you will still get perfect thumbnails, but only part of the full-size image.
This is a part of the EXIF format, which is used by virtually all digital cameras and is also responsible for embedded camera type and settings, which you can see in Windows file properties and many programs, when viewing digital photos.
