Android is a great mobile operating system but it is a bit of a privacy nightmare.
But with a bit of effort and maybe a few compromises it can be vastly improved.

I couldn't find a quick way to create a webpage with all the images in a photo album.
I created a little script to help with this. It's a bit crude but it works, mostly. I have updated it a bit to improve performance when there are a lot of pictures in the database.

The script is in node.js as recommended by a friend for the ease of calling the API and JSON parsing. I didn't know anything about node.js three hours ago so it is a bit messy.

The photos are already uploaded to an album!

I call the script like this
node orderedalbum.js server_url user password album_name > out

The script gets the URL encoded version of the album name then gets a list of all photos in the album and sorts them by name. I then copy the output into a Hubzilla webpage and I have a page full of images. That's how I did this page: https://www.moonskin.org/page/yann/travel-2017-lviv

 if( process.argv.length != 6 ) {
  console.log("usage: orderedalbum.js server user password album");
  process.exit(1);
 }
  
 var server = process.argv[2];
 var user = process.argv[3];
 var password = process.argv[4];
 var thealbum = process.argv[5];
  
 var request = require('request');
 var url = server + '/api/z/1.0/albums';
  
 request(url, function (error, response, body) {
  if(error != null)
  console.log('error:', error);
  if( response && response.statusCode != 200 ) 
  console.log('statusCode:', response.statusCode);
  obj = JSON.parse( body );
  
 //console.log('albums:', obj);
  for(var idx in obj.albums) {
  if( obj.albums[idx].text === thealbum ) {
  var albumencoded = obj.albums[idx].text;
  }
  }
  
 url = server + '/api/z/1.0/photos?album=' + albumencoded;
  
 request(url, function (error2, response2, body2) {
  if(error2 != null)
  console.log('error:', error2);
  if( response2 && response2.statusCode != 200 ) 
  console.log('statusCode:', response2.statusCode);
  obj = JSON.parse( body2 );
  
 var photolist = [];for(var idx in obj.photos) { if( obj.photos[idx].imgscale == 1) { var photo = {name: obj.photos[idx].filename, src: obj.photos[idx].src, height: obj.photos[idx].height, width: obj.photos[idx].width, res: obj.photos[idx].resource_id}; photolist.push( photo ); }}photolist.sort(function(a, b){ if (a.name < b.name) {return -1;} if (a.name > b.name) {return 1;} return 0;}); for (i = 0; i < photolist.length; i++) { var link = "<!--" + photolist[i].name + "--> [zrl=" + server + "/photos/" + user + "/image/" + photolist[i].res + "][zmg=" + photolist[i].width + "x" + photolist[i].height + "]" + photolist[i].src + "[/zmg][/zrl]"; console.log("%s\n",link);}
  
 }).auth(user, password, false);
 }).auth(user, password, false);

The script is attached to this article.
