the image is corrupt. The error is from the FromStream method. Can you write to disk and see if you can open it in an image view. If not then check the code where you are inserting it into the database

Byte[] bytePicData = (Byte[])dt.Rows[0]["PICTURE"];
// Save
File.WriteAllBytes("out.bmp", bytePicData);

MemoryStream stmPicData = new MemoryStream(bytePicData);
PicBox.Image = BitMap.FromStream(stmPicData);
