How do I change order of photos in Photos app?

I would avoid the media picker, if an app does not support it well:

• For apps, that have an own sharing extension for Photos, like Mail, I would select the photos directly in Photos and then use the Share menu to call the sharing extension.
• For other apps I would export the items I want to share to a folder on the Desktop and then call the app and import the photos.

Exporting the photos would have the added bonus that we can specify the resolution and quality of the shared items.

I get that. But in either case, for me, the newest are first, whether that's on top or bottom. From your screenshots, it looks like that's exactly the case for you.

Like this example of an upload in Safai, the most recent pictures appear first, and they are at the top. So the only change is that you have to scroll a different direction to get to old pictures, is that right? That can't be changed.

As a side note, I dont use 'albums' to store any photos...the photos I have are almost all regularly deleted and replaced with new...

Frankly, one of the most powerful features of Photos is its organization features, like albums, folders, searches, and so forth. But I see that you have no use for those. In that case, you could just put picture files in Finder folders and use an app like Preview to handle them. For that kind of stuff, like editing and arranging example screenshots like above, I actually use the app GraphicConverter ($40,) because it's very versatile, and I've used it for thirty years! But anything you do that's different requires practice, of course, so it may not be worth it to switch. So this is more example than suggestion!

Good idea, but the problem is with the media picker like in Safari, and that doesn't work with albums-- it just uses the Library.

Than do what I used to do: add a unique keyword to the photos I want to upload. Then use the search field to search for that for that keyword. It worked like a charm n Ventura. However, running Sequoia, I just tried to add an image to this post with the Image Insertion button and it would not let me access my Photos library. ♬The times they are a changing.♪

If you want to see all of your items in the library with newest on top or on the bottom create a smart album like this:

Then you can sort the items any way you'd like except manually.

As far as I can tell, in both cases the most recent pictures are in the place you see first. In Photo's Library view we have to scroll up to see the older ones, and in Safari's media picker we have to scroll down to see the older ones. I'd think that almost everybody wants to see the most recent first, and that happens either way.

Are you really wanting the oldest pictures first so that you have to scroll all the way through old pictures your grandparents made to get to the new ones? I doubt that's going to happen, but you can make suggestions to Apple here:

The following screenshot shows the various sort options for the various views in a Photos library:
