Creating a new form in a list by copying an existing form (in code)

To copy an existing form in a WSS list, and to add a new content editor web part to that list, use the SPFile class (not the SPForm collection of the list):

//Copy the NewForm.aspx to NewForm_new.aspx
string formPath = "Lists/ClientTest/NewForm.aspx";
string newformPath = formPath.Replace(".aspx", "_new.aspx");
SPFile form = web.GetFile(formPath);
form.CopyTo(newformPath, false);

//Get a reference to the new form, and create a new content editor web part containing onload JavaScript
SPFile copiedForm = web.GetFile(newformPath);
SPLimitedWebPartManager wpManager = copiedForm.GetLimitedWebPartManager(PersonalizationScope.Shared);

//Create the new web part
ContentEditorWebPart wpContent = new ContentEditorWebPart();
XmlDocument xmlContent = new XmlDocument();
XmlElement el = xmlContent.CreateElement("El");
el.InnerText = "";
wpContent.Content = el;
wpManager.AddWebPart(wpContent, "Main", 0);

The JavaScript adds an onload handler to the page, allowing for behaviours to modify the content of the standard list form for example.

Glad you find my scribblings useful!

The SPPictureLibrary class is the one that you need. Have a look at SPPictureLibrary in MSDN for details.
