extends FilterInputStream
implements Runnable

IECompatibleJpegInputStream removes additional information left by PhotoShop 7 in jpegs , this information may crash Internet Exploder. that's why you need to remove it. With PS 7, Adobe decided by default to embed XML-encoded "preview" data into JPEG files, using a feature of the JPEG format that permits embedding of arbitrarily-named "profiles". In theory, these files are valid according to the JPEG specifications. However they break many applications, including Quark and, significantly, various versions of Internet Explorer on various platforms.
