Hi!

I have two questions about loading the panorama:

1. Does panorama loading time depend only on the internet connection or are there some things I can do to make it load quicker? Especially on slower internet? My output folder is about 160 Mb so it's not big. My image output Html settings are also standard with quality - 90, multiresolution, etc.

2. When the panorama is loading, before photos are loaded I can see all SVG images and nodes loaded. Sometimes panoramas take some time to load and for me, preloaded SVG and png images alone look like a mess. Is there a way to make a load screen that maybe takes some more time but at the end shows a fully loaded panorama not the part of it?

Hi Mario,
For the panoramas, using multiresolution is much better as it downloads for the resolution of the viewport with no zoom.
Then as you zoom in it can fetch higher resolution images so staggering the download.

Looking at your link on open it is downloading just over 17MB.
Which for me is around 3 seconds @ 60 MB download speed.

The biggest problems you have is the sizes of your images that are preloaded.
As an example, this one: https://lemonpic.pl/spacer3d/7/media/bi ... 2021-5.jpg
This is 2,481 x 3,473px, this is far too large for iOS and Android and may possibly crash mobile browsers.

There is a developer doc somewhere that says you shouldn't go above 1024ps in the longest direction for an image or video in iOS.
Also, the Memory also determines what resolution it will open or crash.

To be safe I tend to keep images below 900px

Preloading media such as the background music, Chopin Nocturne Op.9 No.2 (Arthur Rubinstein).mp3
This is 10.20MB, this seems to stream nicely, but in the past, we have seen badly encoded MP3s that have to be completely downloaded before that play.

As a side note, I saw a lot of spaces in file names, on the web, a space is represented as "%20", so looks really ugly.
It is much better to use an underscore, so

as opposed to
