example:
int width, height;//set some widht & height
DataRow dr;//assume you have data from db in dr.
System.Drawing.Image img = (System.Drawing.Image)imgConverter.ConvertFrom((Byte[])dr["img_person"]);
Bitmap bmp = new Bitmap(img, new Size(width, height));
Response.ContentType = "image/GIF";//gif or other format
bmp.Save(Response.OutputStream, ImageFormat.Gif);//gif or other format

do this in popup's page_load event. Remember this is Response content. So you will have whole page with just one image. If you would like to display multiple images in a page this does not work as is. You may have to do diff. way.
