Data image - ReadAllBytes TimeOut

Templates, (partial) views and macros

Umbraco 7

Hello all,

I have an issue whereby I am trying to create a data image but encounter an timeout issue when rendering the page.

Can someone please shed some light as the possible reasons why?

Here is my code below:

    // Loop sections
    foreach ( var item in @node.DescendantsOrSelf("Section") )
    {
        string image = "....path....";

        byte[] array = System.IO.File.ReadAllBytes( Server.MapPath(image) );

        string baseCode = Convert.ToBase64String(array);

        contentList.Add( string.Format( 
                @"{{ text: ""data:image/jpeg;base64,{0}"" }}",  
                baseCode
            ) 
        );

    }

Encase anyone needs help, this was my solution:

using ( MemoryStream ms = new MemoryStream() )
{
    var webClient = new WebClient();
    string imageUrl = image;
    if ( type == "local" )
    {
        imageUrl = "https://" + @HttpContext.Current.Request.Url.Host + "/" +image;
    }
    byte[] imageBytes = webClient.DownloadData(imageUrl);
    return Convert.ToBase64String( imageBytes );
}
