    Powershell to download Dungeon, Dragon, and ArtGallery from D&D Insider

    Needed to learn some PowerShell stuff, so practiced by creating PowerShell that will download all the Dungeon magazines, Dragon magazines, and Art Gallery files from D&D Insider. Requires a current DDI subscription.

    Will create "Dungeon", "Dragon", and "ArtGallery" directories under whatever directory from which you run the commands.

    In PowerShell, paste the code below. Change the $username and $password variables to your DDI login info, then type "download" and hopefully it will download all the files. It is a bit slow (took nearly an hour for me.)

    (Do not try it as a script because Windows has PowerShell scripts turned off by default and I did not test it as a script so not sure if it will run as a script.)

    Code:
    [Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
    
    
    $ddiBaseUrl = "https://ddi.wizards.com"
    $dragonUrl = $ddiBaseUrl + "/ContentArchive.aspx?type=Dragon"
    $dungeonUrl = $ddiBaseUrl + "/ContentArchive.aspx?type=Dungeon"
    $artUrl = $ddiBaseUrl + "/ContentArchive.aspx?type=ArtGallery"
    
    
    function BuildAuthenticationInfo($loginForm)
    {
     $body = "__EVENTTARGET=" + [uri]::EscapeDataString($loginForm.fields["__EVENTTARGET"])
     $body += "&__EVENTARGUMENT=" + [uri]::EscapeDataString($loginForm.fields["__EVENTARGUMENT"])
     $body += "&__VIEWSTATE=" + [uri]::EscapeDataString($loginForm.fields["__VIEWSTATE"])
     $body += "&__VIEWSTATEGENERATOR=" + [uri]::EscapeDataString($loginForm.fields["__VIEWSTATEGENERATOR"])
     $body += "&__EVENTVALIDATION=" + [uri]::EscapeDataString($loginForm.fields["__EVENTVALIDATION"])
     $body += "&ctl00%24ctl00%24ctl00%24ctl00%24SiteContent%24DnDContent%24MainDnDContent%24LeftColumn%24UserName=" + [uri]::EscapeDataString($username)
     $body += "&ctl00%24ctl00%24ctl00%24ctl00%24SiteContent%24DnDContent%24MainDnDContent%24LeftColumn%24Password=" + [uri]::EscapeDataString($password)
     $body += "&ctl00%24ctl00%24ctl00%24ctl00%24SiteContent%24DnDContent%24MainDnDContent%24LeftColumn%24Login=GO"
     return $body
    }

    I am going back into 4e and trying to sort out my content collection.
    I was wondering if anyone has kept any of the ArtGallery images from DDI ?

    That sounds awesome. DM me if you ever find it or someone who has it, I'd love to look at all the old art. I came into 4e this year with kind of a weird path (went from 3.5 to Pathfinder 1e to 5e to Pathfinder 2e to now trying out D&D 4e and 5.5 at the same time) so I never even had a DDI subscription before they shut it all down.
