Help: Need script for Raspberry Pi digital photo frame

So I wanted a digital frame, and they were crazy expensive. So I bought a Raspberry Pi 4 and a monitor. The Google Photos slideshow option is stupid fast, and can't be changed.

I found this script online to just auto change the photos without using slideshow. I am using Greasemonkey on firefox.
Website: paulstamatiou.com...

// ==UserScript==
// @name google photos slower slideshow
// @namespace piframe
// @include photos.google.com...*
// @version 1
// @grant none
// ==/UserScript==

// CHANGE first_photo TO USE THE URL OF THE FIRST PHOTO IN YOUR ALBUM
var first_photo = 'https://photos.google.com/album/XXXX/photo/XXXX';

// how often to change photo, in seconds
var interval = 60;
function pressKey() [
var key = 39; // right arrow keycode
var ke = new KeyboardEvent("keydown", [
bubbles: true, cancelable: true, keyCode: key
]);
document.body.dispatchEvent(ke);
]
function next_or_prev() [
var current_url = window.location.href;
pressKey();
// I think there is a race condition with the URL updating after keypress, so we need to delay this slightly.
setTimeout()[
if (current_url == window.location.href) [window.location.href = first_photo;]
], 100);
]
window.setInterval()[next_or_prev()], interval * 1000);

The problem is it does not work. Anyone know why?

I used the URL of my google photo album and put it in place of the * for album name, and I used the URL of the photo in place of the * for photo name.

var interval = 60

Isn't that milliseconds ?

a reply to: StallionDuck

Perhaps use Setinterval or setTimeout?

function timeout() [
setTimeout(function () [
count += 1;
console.log(count);
timeout();
], time);
];
timeout();

Seconds it says. The 1000 on bottom is milliseconds. (that's what it says at least)

a reply to: OccamsRazor04

That's where I would be confused. 1000ms = 1s

Seems like the number would be 60000 for 60 seconds.

Don't take my word for it though. I only really 'edit' C# code. I never put the time in to actually write the stuff myself. I can do basic all day long, surprisingly still from many, many years ago but new coding languages - not so much. I can break it down and edit them to my needs but my mental database isn't that large. Though... Still... It has it's similarity to basic enough to where I can at least get into trouble.

a reply to: StallionDuck

The interval variable is multiplied by 1000. The code is _javascript. SetTimeout in _javascript is milliseconds.

Does the page show nothing or it just does not advance the slideshow? I really do not understand what you mean by "it does not work".

*sigh* ... let me create a google photos account and ill debug this in firefox. This code should work across pretty much all browsers the same. Its not like its coded in raspian for petes sake...

a reply to: OccamsRazor04

I dont see any problems with this code unless maybe you were not authenticated to the site in the browser to begin with.

The last function I would write more like this if it was pure _javascript but I dunno how this would pan out with greasechimp.

paste bin link to code how I would write that last function

I just found out you cannot link pastebin I guess.....

Truly though, I think this should be written into googles photos API to authenticate, retrieve a list of albums, allow you to set the albums in a config file either permissive or dismissive in an array. Then retrieve an array of all photos per album and iterate through them all using the REST methods and _javascript xhr get/post requests. You can do it!! If you need help on that one let me know.

I can only imagine Google changed something. I've decided to just not stream the photos and use a flash drive. Now I just need Kodi running smoother.

a reply to: OccamsRazor04

the script actually worked for me so I dont think its a google thing. Maybe a firefox version thing or something though. I wouldnt stream for the sake of bandwidth on my hi res photos. If you want to access a local or network storage and display files in a browser window you could code this pretty easy with python.

Whatta ya know... its already out there.

github.com...

Thank you I will look at that!

Why not just a screensaver to your photos?
