I'm guessing this means I could make a replacement GIF codec to replace the built-in one, but before I do I need to know something. But since the photo viewer uses WIC (Windows Imaging Component) to decode images, this system can be used to add support for just about any format. People have suggested various third-party software (AKA not the built-in windows photo viewer) to solve this shortcoming. Am I crazy or does nobody else have this problem too? So many decisions by this company confuse me to no end. How did anyone think releasing this incompetent app was a good idea? Especially as the old photo viewer app had no problems. After many discussions with my peers, trying out other people's computers and buying a new laptop I am convinced it is a problem on Microsoft's side. It is absolute garbage but I thought it maybe has something to do with my computer. Or you can send here two files - rotated and original - and I'll check this out.Ībout two years ago I bought a new computer and it was installed with the new Photos app. Look especially at info about binary data. You can look at the exiftool info (exiftool filename.jpg) and compare if metadata got changed.

In this case photo wouldn't be touched, but metadata - precisely "photo in photo". Some cameras adds really big thumbnail to JPEG files and Windows either removes it or changes it to own. Why size has changed? It's hard to tell without file. If your image browser have Exif rotation tag support, you'd see both photos the same. If you see both photos rotated it means that one have Exif rotation tag and second one is really rotated by Windows. Second one manipulates image data ("real" rotation), but without loosing data*. It's just data for image browser that it should show image rotated. Photo can be rotated losslessly in two ways (maybe more?).
