I recently downloaded a picture from LinkedIn, and something really weird happens with it. Let me just state before that I can't show you the author asked me don't show it.
So, if I do "read informations" of the picture, it is 139 x 139 pixels. I can open it everywhere, it will have this square shape and this 139 x 139 size. But, when I look at it on my computer desktop, it appears way larger, and not even squared. It is in horizontal rectangle shape, and if I enlarge the thumbnail size, it shows way more than what I can see in Preview, photoshop, and every applications that can read pictures (it is not an impression, it really shows outside the square).
So I opened it in an exif reader, and in it, it says the size is actually 2048 x 1536, and the preview of the image is now as the thumbnail . I also tried to open it in chrome, and send it to an exif viewer extension, and the extension crashed every time I tried.
I searched for this type of problem, and I found nothing. Some people told me to use an hexadecimal reader, but I have no idea of how it works.
I need help try to get this picture in the size showed in the thumbnail . Thanks for your help :)
