let
    //Get list of files in folder
    Source = Folder.Files("imagas_path"),
    //Remove unnecessary columns
   RemoveOtherColumns = Table.SelectColumns(Source,{"Content", "Name"}),
    // Creates Splitter function
    SplitTextFunction = Splitter.SplitTextByRepeatedLengths(30000),
    //Converts table of files to list
    ListInput = Table.ToRows(RemoveOtherColumns),
    //Function to convert binary of photo to multiple
    //text values
    ConvertOneFile = (InputRow as list) => 
        let
            BinaryIn = InputRow{0},

            AddFileName = List.Transform(SplitUpText, each {FileName,_})
        in
            AddFileName,
    //Loops over all photos and calls the above function
    ConvertAllFiles = List.Transform(ListInput, each ConvertOneFile(_)),
    //Combines lists together
    CombineLists = List.Combine(ConvertAllFiles),
    //Converts results to table
    ToTable = #table(type table[Name=text,Pic=text],CombineLists),
    //Adds index column to output table
    AddIndexColumn = Table.AddIndexColumn(ToTable, "Index", 0, 1)
in
    AddIndexColumn
