I want to state once and for all, that a document leading me to the above result is not helping, it is not an instruction which lets me advance towards a solution to my problem and it is useless to point me there in the first place.

Remember that JPG image file is popular because of its fast speed and compatibility with different devices used today." There is little you can do in these cases because the problem is at the server end.

Use these programs to open JP2 (JPEG 2000) files on Mac:

It is, thus, it’s best to convert JP2 to JPEG quality image file to achieve maximum results. Typically, the JP2 file format is not highly compatible with most devices and browsers. No doubt that JP2 and JPG file formats provide you with the best compression ratios. However, if you could prefer regular JPEG images instead of JP2, then our JP2 to JPEG converter is the best choice. The JP2 algorithm uses an “area of interest” based approach and that’s the reason why it makes it possible to save parts of the image in different quality.

JP2 has been created to supersede the existing JPEG standards. It is referred to as an image file compression algorithm that using the technology of wavelet transform. It can be a picture, an image that comes from a surveillance camera, digital fax, and others. JP2 is indicated as a bitmap image format JPEG 2000.
