That's not what is happening at all.
When you take a photo, your phone or camera stores it in
EXIF format, which has an orientation attribute included somewhere in the camera settings metadata.
The upload scripts convert EXIF format images to JPEG, for a number of reasons. One is that EXIF (and TIFF and other similar formats) can contain non-visible data. Converting to JPEG only keeps the image data, which is safer.
The recommended way to upload images is to open them in any photo editor — I use
GIMP —, cropping the image to focus on the useful part of the image, and resizing it (the pixel size, not the print size) to minimize the file size. The required size depends on the complexity of the image. Just look at the cropped-and-scaled image at 100% to see if it looks good enough; undoing and trying another size until you're satisfied. (Do not repeatedly resize an image; that loses information. Always "undo", and resize the original, cropped image instead.) Finally, save it in JPEG format. Again, you may wish to experiment with the Quality setting; lower quality produces softer/blockier images, but higher quality increases file size. Adjust until optimal in your opinion.
If you don't want to do any of that, and just post images off your phone for a "quick post", I'd wager that your post does not have enough thought in it to be useful to anyone other than yourself anyway, which means it should not be posted at all. Even your "test image" is 4000×3000 pixels, way larger than is necessary, and over 2 Mbytes in size!
(If I was on my old, slow-connection phone, it'd take several seconds to load.)
Put bluntly, you're asking the admin to paper over the issues in the images you want to post. Please, don't.
Going the extra step to make your images useful and lightweight for others shows that you care, and that your post is worth considering answering. Not doing that indicates the opposite. When I post a photo (I rarely do — I usually post diagrams, and those are sharper and better when saved in optimized PNG format, for which I use the "pngcrush" tool to minimize file sizes; or in vector-graphics SVG format, which I store at my
own webhost for security reasons, avoiding any XSS etc. attacks via such images on eevblog.com), I take a few photos, open them all in GIMP, crop them all, then look at 200% to determine which one has best fidelity (least blurring), then resize/rescale that to optimum size, never larger than 2000 pixels in size on the longer edge, and finally save as JPEG in four or five different quality settings. I open them all, and examine at 200%, discarding the ones that got too blurry. I pick the image with the smallest file size left over.
It can sound like "extra work", but what it is, is
consideration for others, showing that you care about others, and are not here just to leech from others to minimize any effort needed on your part. All useful discussion is a give-and-take.
If this sounds "unfriendly", it is not intentional; this is just what I've learned works best, that I apply to my own output first before asking it from others. You might wish to read my similar advice in the pinned
