Thanks for your offer of help. I'm using an iPad Pro and don't know how to resize it, compatible with this site. Help is appreciated. Nice community!
Well I'll be hornswaggled.
My wife has an iPad Pro (just a month or so old, and it's her third or fourth iPad over the years), and I was just playing with it, in the Photos app. After failing miserably and doing some research, I learned that there's no Resize function in Photos on iOS. Color me surprised.
It turns out that you can resize a photo on an iPad, with Apple's built-in software called Shortcuts. But, man, what a lot of hoops you have to jump through. Here's what I think is one of the better (and up-to-date) discussions on that:
From this article, you get to know how to resize photos directly from iPhone using Shortcuts and a cropping feature. Read it to discover one more way!

Now, on the other hand, if you have probably ANY third-party photo-editing app on your iPad, you can probably just click on the photo and choose "Resize" from a menu. Much easier. I have half a dozen or so photo-editing apps on my Mac, and they all have that sort of easy-to-use function (along with contrast, saturation, exposure, yada yada, i.e., the same sort of choices that you find in Photos on an iPad when you click on Edit ... except that Photos doesn't have the Resize choice). Same thing with photo editors on PCs, which I've used since right about when they were born.
So, if you can find a low-priced or maybe free (or maybe free for a week) photo editor in the App Store, I would suggest that you try one out on your iPad. I think "photo editors" would be a good Search term in the App Store.
And then use that third-party app to do your resizing to post photos here. As I say, resizing from 4000 x 3000-ish pixels to 1000 x 750-ish pixels will drop a typical photo's size down from 2 or 3 MB to 200-ish KB, just by doing that resize function, and that's an acceptable size for the forum here, and will be just fine for viewing on a forum (I mean, no one's going to save the pic and then try to do a poster-size print of it). You won't have to change the quality in any other way, and it'll be fine here.
You can also try mailing it to someone else, when you sometimes get asked if you want to send a pic in its original size or some smaller size, in the world of Apple. I tried doing that tonight, along with texting it to myself, but it looks like you don't get asked that size question if you're on the same wi-fi network as yourself.
Sorry that this is such a PITA on the iPad and iPhone. Me, we're an Apple family, with two iPhones and the Mac, along with my wife's iPads, but I do all the photo work -- enhance exposure values, that sort of post-processing trickery, on the Mac here (my second one, and with a real keyboard from Das Keyboard that I substituted for the chicklet thing that came with it).
