Tom Tee,
What computer are you using, PC or Mac? What you describe happening is a function of your editing software, not the forum. What's most likely happening is when you save your edited on your computer, it is also saving the original EXIF file with it. The EXIF file has all the original data, especially orientation, from the original photo as downloaded from your camera.
Some websites don't look at EXIF, others do. My guess is Hoopla does. Not a fault, just the way they decided to code.
So, even if you edited a right side up picture to appear upside down, when you upload it to a site that read the original EXIF information, that upside pic would show up online right side up, as you took it.
This is also why your pics upload the way you want on other sites. Those sites don't look at EXIF orientation info.
Depending on your camera and editing software there's a couple way to "fix" this.
1. Do not use auto orientation
2. Your software may have a box to check that says "save EXIF?" when you go to save your edited photo.
Hope this helps.
