Support for JPEG compression is localized to the JPEG plugin. It's not part of Image.
If you load a JPEG file, OSG's JPEG plugin uses the third party libjpeg, under the hood, to decompress your data into an array of pixels. Then it stores that raw pixel data in an Image and returns it to your app. If you load the JPEG yourself, then you must also decompress it yourself (using libjpeg or some equivalent functionality). Then call Image::setImage() and pass in the uncompressed pixel data.
