Hello Chaudhary I am not sure what you mean by "Bio page" are you referring to the details page for each individual user? Or is Bio some custom page type? If you have the MediaFileInfo object you could simply build the url using everything inside the object, something like this:
string url = MediaFileURLProvider.GetMediaFileUrl(mfi.FileGUID, mfi.FileName);
url = URLHelper.AddParameterToUrl(url, "width", mfi.FileImageWidth.ToString());
url = URLHelper.AddParameterToUrl(url, "height", mfi.FileImageHeight.ToString());
url = URLHelper.AddParameterToUrl(url, "ext", mfi.FileExtension);
