Ray, that sideways thing has been discussed before. I'm not technically educated so I might use bad terminology but here's the deal. If I take a photo with my phone or tablet (iPhone/iPad) the digital images are stored with a set of information regarding size and orientation and probably other stuff too. Like I said, I don't know the lingo and GAD got me through this. So if you try to upload that photo, the software here just flips it sideways. I don't know why. If I send the photo to my computer even, it goes with this set of information or instructions (help me anyone if I'm getting this totally wrong) so same thing if I upload from the computer. I never send from my phone to the computer as "full sized" (an option on i-Things) because I know it's going to be too big to post, so I do Large or Medium.
Now, from my computer, I pull up the photo into a program used for photo editing. My Dell with Windows 10 has one I'm sure. I use IrfanView (have for years, it's great and free to download and also good for file and batch file conversions) and open the photo in that program. Now, what has to happen is I need to get rid of those phone/tablet instructions imbedded in the photo that cause the photo to flip. The only way I know and easiest for me is to resize/resample (terms may be different in different programs) the photo. Not much, just a bit. So with the photo open in IrfanView, I select "resize/resample" and it brings up the window with the data about the photo. Size (in pixels, inches, cm's, I chose which one) and then it displays how many pixels wide and tall the photo is. I need to CHANGE THE SIZE of the photo because somehow that removes the info in the photo that makes it flip. There is a box there that should be checked called "preserve aspect ratio (proportional)". That means it keeps the width and height in proportion so it doesn't distort the photo. Let's say it says the current height (or width, you only have to change one because of the box you checked) is 1032 pixels (or inches or cm's). I just highlight it and make it 1000. A small reduction but it enough to remove the code that's in the photo. Then I hit the "OK" button for the changes I've made and then you have another decision to make. It's going to ask you what you wanna name the photo and where you want it. At this point you have to decide if you want the original to stay the same and also make this new copy that you can post. I don't, I just select the same name and location and again hit "Save" and it says "This file already exists, do you want to replace it?" and I say yes or okay. Now the photo is saved without the code that makes it flip when posted to the site. It sounds more difficult than it is. The only thing is do you want to make two sets of photos and how are you going to distinguish between them? By naming it differently, or in a different location, or both? That's up to you.
Now when I post the photo, it doesn't flip when posted to LTG. You can probably do this same thing on a phone or tablet if you have the same programs on them to do this. But I do my posting from my computer and accessing the site (mostly) from my computer.
I'm sure there are other ways to look for the code and info that's in the photo and remove it but that takes more skill and knowledge than I have. So this is the easiest way I know.
Does this help you?
Also, once GAD moves the site and does the upgrades that are planned (expect some interruption in site access at some point, it's coming) maybe we won't have to do all this, I don't know.
