Now I am using the Varilable
initializeWeb Photos which is being used with the Web(WebPhotos) to get 1 url From a google appscript which it returns a Json only when there are new photos in the google sheet.
when it is called first time it returns : ["https://drive.google.com/uc?export=download&id=1eEnu_JZbHr3ppXSJteditedV6TytDot1T","https://drive.google.com/uc?export=download&id=1RVelGxI1TjBRKhjeditedLBNVDwpwrPpW","https://drive.google.com/uc?export=download&id=1nsKPKjA0LDiIXNFeditedbSQ2REjHortq","https://drive.google.com/uc?export=download&id=1oWlPmYHXNXHNeditedbJu2AFblEqjCP70"] if there are no new photos Then it returns nothing.

Then with the WhenWebPhotos.Got Text im doing a Json Decode in order to creat a list with the Urls Named GlobalPhtotoUrlsList which will be used next for Caching
Then When Weburls.GotFile (newWebComponent) in order to be used to download the photos from Urls and it is calling the StartSingle Download procedure to download each list.
And finaly i want to display those photos in 4 images in random to change randomly every 30 sec.
Do you have any idea why the Urls are note saved to path and i am not able to use the app?
How it sould be like:

To download files using the web component you must set saveResponse = true, and provide a filename for each file with responseFilename = ....

Depending on Android version you must set the filescope correctly.

See here for file by file download examples:

Did you checked the photo of the code? in order to give me more specific directions?
Do you know any extention to do that easyer ?
I have asked also chat Gpt - and Gemini but both ai did not helped.
May i use your extension
WebViewExtra - Upload/Download Files with webviewer
in order to create a list with the the Downloadble Urls after the Json Decode and to store them and then to be used for downloading and store the images in a local file?
