string iptc = "";
textBox1.Text = openFileDialog1.FileName;
app = new Photoshop.ApplicationClass();
app.Visible = false;
app.DisplayDialogs = PsDialogModes.psDisplayNoDialogs;
app.Application.Visible = false;
ps = app.Open(openFileDialog1.FileName, null);
//app.ActiveDocument = ps;

foreach (Photoshop.ArtLayer artlayerRef in ps.ArtLayers)
{
artlayerRef.Visible = false;
}

//ps.SaveAs("D:\\psaveimage", jpgs, null,2);
psi = ps.Info;

iptc = psi.Author.ToString() + "|";
iptc += psi.AuthorPosition.ToString() + "|";
iptc += psi.Caption.ToString() + "|";
iptc += psi.CaptionWriter.ToString() + "|";
iptc += psi.Category.ToString() + "|";
iptc += psi.City.ToString() + "|";
