bug report == or at least it is to me Answered

I use Corel  Photo Paint 16 to edit all my pictures. It is running on a fast Windows 7 system. I often shoot pictures sideways with my camera for a better use of the rectangle format. It is a DSLR by Olympus.  So when I edit the pictures I rotate them and fix contrast and everything. I also reduce the size since the camera takes things at the max resolution. 
But a strange thing happens when I upload the pictures to instructables. It changes the orientation back to the original. All the cropping and contrast adjustments are there, but the pictures are sideways. Not just the thumbnails the entire picture. So I have to go through them and use your online edit program to rotate them back to where they should be. This is sometimes a problem when I am trying to put up a new instructable and I have a lot of pictures and I have to spend a lot of time re editing the pictures again. What is an even bigger problem is when the online program messes up and I have to just post things sideways until the program starts working correctly again. I almost missed the deadline on a recent contest because of the pictures needing to be fixed.
Any clue as to what might be causing this?

Corel Photo Paint has a long history of messing up exif data (try googling "corel photo paint loses exif data"). An easy way to test this theory: upload a photo straight from your camera to Instructables, without opening it first in PP. If it's rotated incorrectly coming off of your camera, just paste a link to the file here and we can take a look at what's going on.

Looking at https://www.instructables.com/file/FHJIR27IPOA40LD/ I have to say I was mightily confused. The file displays upside down as the "original", rotated left in other sizes, and right-side-up in the *thumbnail* when I download it to my mac. When I open the same image whose thumbnail displays correctly, it's upside down again, both in preview and in photoshop. There's something funky going on there. One way to eliminate possible causes would be to remove the exif data entirely:

http://www.makeuseof.com/tag/3-ways-to-remove-exif-metadata-from-photos-and-why-you-might-want-to/

You can also easily view all the exif data here: http://metapicz.com/#landing

In the case of this image, the "orientation" is "Rotate 270 CW" ... which wouldn't yield a right-side-up image for any of the orientations that I've actually seen displayed.

Lastly, I did quite a bit of work myself to make sure that a wide range of exif orientations are supported by this tool: http://strandedcity.github.io/jimp/browser/ ... which displays your image upside-down.

In short, I think there's something in your workflow that's introducing some corrupted rotation information, likely Photo Paint. If upgrading PP is an option that could be worth a shot, and if you can upload an image that did *not* go through this flow but does get rotated wrongly, I'd love to dig in deeper.

Good luck!

Also: A work-around if Photo Paint is the culprit but you like the workflow: don't rotate the image before you save it. Upload it to us "sideways", and see if it comes in straight.

I bet Photo Paint is keeping the exif data, but not updating it when you apply the rotation. So you rotate once, and we rotate again because the "rotate me!" flag is still set.

What file format were the pics? I remember there were glitches with PNGs once and some wonkiness with my iphone images being rotated back when uploaded. Using jpeg format seems to avoid any problems.Of course, I have to export that out when I do my stuff in GIMP.

Although Corel has their own format I always save everything as JPEG since it is universal. So everything is in JPEG format , and my Firefox is up to date.
