Hi Marco Holzer,

images are accessed per entry. Exporting them is very easy, importing a bit more complex: add the image itself to the termbase storage, and then add a field linking to it to the entry. Code is clearer than explanations, so here we go. This assumes your termbase has a multimedia field called "imageField" at the entry level, and you want to edit the entry with id 3

Sdl.MultiTerm.TMO.Interop.Application _mt;
TermbaseRepository _tr;
Termbase _tb;

public void runTests()
{
    int entryId = 3;
    Init(@"E:\_temp\media.sdltb");
    AddImageSample(entryId, "imageField", @"E:\_temp\p3.jpg");
    ExtractImageSample(entryId, @"E:\_temp", "mediaexport");
    Exit();
}

private void Init(string termbasePath)
{
    _mt = new Sdl.MultiTerm.TMO.Interop.Application();
    _tr = _mt.LocalRepository;
    _tr.Connect("", "");
    _tr.Termbases.Add(termbasePath, "", "");
    _tb = _tr.Termbases[termbasePath];
}

private void Exit()
{
    _tb.Close();
    _tr.Disconnect();
}

private void ExtractImageSample(int entryId, string targetFolder, string subfolderLabel)
{
    Entry en = _tb.Entries.Item(entryId);
    en.ApplyExportWithMultimedia(_tb.ExportDefinitions["Default export definition"], "", "", targetFolder, subfolderLabel);
    // or alternatively, to system temp folder
    en.ExtractMultimediaToTemp();
}

private void AddImageSample(int entryId, string fieldName, string imagePath)
{
    int mediaId = StoreImage(entryId, imagePath);

    Entry en = _tb.Entries.Item(entryId);
    EntryContent ec = en.Content;
    ec.Content = AddImageToEntryField(ec.Content, fieldName, mediaId.ToString(), imagePath);
    en.LockEntry(MtLockingState.mtLock);
    ec.Update();
    en.LockEntry(MtLockingState.mtUnlock);
}

private string AddImageToEntryField(string entryContent, string fieldName, string mediaId, string path)
{
    XmlDocument doc = new XmlDocument();
    doc.LoadXml(entryContent);

    XmlNode conceptGrpNode = doc.SelectSingleNode("conceptGrp");

    XmlNode descripGrpNode = doc.CreateElement("descripGrp");
    conceptGrpNode.AppendChild(descripGrpNode);
    XmlAttribute attr = doc.CreateAttribute("multimedia");
    attr.Value = mediaId.ToString();
    descripGrpNode.Attributes.Append(attr);

    XmlNode descripNode = doc.CreateElement("descrip");
    descripGrpNode.AppendChild(descripNode);
    attr = doc.CreateAttribute("type");
    attr.Value = fieldName;
    descripNode.Attributes.Append(attr);
    descripNode.InnerText = Path.GetFileName(path);

    return conceptGrpNode.OuterXml;
}

private int StoreImage(int entryId, string path)
{
    byte[] bytes;
    using (BinaryReader br = new BinaryReader(new FileStream(path, FileMode.Open)))
    {
        FileInfo fi = new FileInfo(path);
        bytes = br.ReadBytes((int)fi.Length);
    }
    string blob = "<?xml version=\"1.0\"?><root xmlns:dt=\"urn:schemas-microsoft-com:datatypes\"><file1 dt:dt=\"bin.base64\">"
        + Convert.ToBase64String(bytes) +
    "</file1></root>";
    return _tb.AddBLOB(entryId, Path.GetFileName(path), blob);
}

Dear Gerhard Kordmann

Many thanks for your response. This looks quite complicated. 

Best Marco

actually, this post should moved into "Developer" area.

if you want to use SDK, you have to familiar with C# and SDL's nice samples.

Mr. Gerhard Kordmann's code is very standard one and clearly written.

Regards
