Hi CJ,
If you add ImageButton to form rather than page, the
ImageButton will be placed inside form tag:
HtmlForm form = (HtmlForm)this.FindControl("Form1");
//...
form.Controls.Add(ImageArray[i]);
//...
Hope it's helpful to you.

You need to give some part of the source code and the error description.
Then only we can figure out.
