There are no size limitations to tokens. The value is truncated to 3700 characters when tracked, but not at runtime.

Thanks for the info Miruna!

Are you able to provide any guidance for merging Forms tables with images into a Word table?

Can you post your Workflow and any scripts you're using? Maher's example works for me with tables too.

Here is the workflow that I am using while trying to prove concept so it doesn't have all the complications of the actual use case. I am grabbing the image file uploaded from the form, saving it to the repository, then running the script (posted below) and attempting to create the document.

Here is the script. I don't 'speak' C# so I didn't write this - it was put together by someone else from our team. But if there is anything wrong, I can certainly update it. 

namespace WorkflowActivity.Scripting.SDKScript
{
    using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Data.SqlClient;
    using System.Text;
    using Laserfiche.RepositoryAccess;
    using Laserfiche.DocumentServices;

    /// <summary>
    /// Provides one or more methods that can be run when the workflow scripting activity is performed.
    /// </summary>
    public class Script1 : RAScriptClass100
    {
        /// <summary>
        /// This method is run when the activity is performed.
        /// </summary>
        protected override void Execute()
        {
            // Write your code here. The BoundEntryInfo property will access the entry, RASession will get the Repository Access session
            String base64String = null;
            try
            {
                // Get EntryID from the FindEntry activity
                //int iDocID = (int)GetTokenValue("CreateEntry2_OutputEntry_ID");

                // PK 10/5/2020 Get the document using the Workflow connection
                using (DocumentInfo DocInfo = (DocumentInfo)BoundEntryInfo)
                //using (DocumentInfo DocInfo = Document.GetDocumentInfo(iDocID, RASession))

                {
                    // Create MemoryStream to hold exported document
                    using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
                    {
                        // Create DocumentExporter object
                        DocumentExporter de = new DocumentExporter();
                        //PK 10/5/2020 Export to Electronic Document
                        de.ExportElecDoc(DocInfo, ms);

                        // Export to PDF in MemoryStream
                        //de.ExportPdf(DocInfo, DocInfo.AllPages, PdfExportOptions.None, ms);

                        // Write MemoryStream data to Base64 string
                        base64String = Convert.ToBase64String(ms.ToArray());
                    }
                }
            }
            catch (Exception ex)
            {
                // Report exception message
                WorkflowApi.TrackError(ex.Message);
                // Set return value to null
                base64String = null;
            }
            // Return the Base64 String
            SetTokenValue("tknImageData", base64String);


        }
    }
}

My SQL column containing the base64 string is configured as nvarchar(max). I also took a screenshot showing how my Word table is formatted. The 'Value' column has been left blank intentionally for testing.
