Retrieve photos on Azure - database

Question

I have a task to do on Azure.
On Azure, I need to get photos with a link like this :
https://picture.blob.core.windows.net/datapicture
I was given this document.
https://learn.microsoft.com/en-us/powershell/module/azure.storage/get-azurestorageblobcontent?view=azurermps-6.13.0
The goal is to make a powershell script that allows you to retrieve photos in this path with Azure.
I don't have a key to login but a login user and password.
My connection model is, I think :
Login-AzureRmAccount
$SourceResourceGroupName = "...";
$SourceServerName = "...";
$Database = "...";
$ServerInstance = "...";
$Username = "...";
$Password = "..."
$con.ConnectionString = "Server=$ServerInstance;
uid=$Username;
pwd=$Password;
Database=$Database;
Integrated Security=False;"
$con.Open();
Thank you in advance for helping me.

Seems that you are trying to download file from Azure Blob Storage. It is not working like a database.
Just as silent explained in comment, Azure Storage supports symmetric key and Azure AD authentication. Or, you can set your file to public in which way it can be accessed directly.
You used Login-AzureRmAccount command. So, you should be able to download a blob as following:
$ResourceGroup = "Jack"
$StorageAccount = "storagetest789"
$Container = "function"
Set-AzureRmCurrentStorageAccount -ResourceGroupName $ResourceGroup -Name $StorageAccount
Get-AzureStorageBlobContent -Container $Container -Blob "User1.txt" -Destination 'D:\'
Update
A normal storage blob URL should look like the following: https://{storage_account_name}.blob.core.windows.net/{container_name}/{blob_name}
So, you may get $StorageAccount, $Container and $Blob as following:
$UserName = '.......';
$Password = '.........';
$Secret = ConvertTo-SecureString -String $Password -AsPlainText -Force;
$PsCred = New-Object System.Management.Automation.PSCredential($UserName, $Secret);
Login-AzureRmAccount -Credential $PsCred;
$ResourceGroup = '';
$URL = 'https://{storage_account_name}.blob.core.windows.net/{container_name}/{blob_name}';
$StorageAccount = $URL.Substring('https://'.Length,$URL.IndexOf(".")-'https://'.Length);
$Path = $URL.Substring($URL.IndexOf('.blob.core.windows.net/')+'.blob.core.windows.net/'.Length);
$Container = $Path.Substring(0,$Path.IndexOf('/'));
$Blob = $Path.Substring($Container.Length+1);
Set-AzCurrentStorageAccount -ResourceGroupName $ResourceGroup -Name $StorageAccount;
Get-AzStorageBlobContent -Container $Container -Blob $Blob -Destination 'D:\';
