add new images for keynote speakers.

[oonid]

refer to #36 please note that:

• the image size should be re-adjust
• both images in a different orientation, don't know which one would be fit

adjust styling sedikit di commit saya sebelumnya mas, tapi masih belum solved main issuenya -> style halaman jadi hancur ketika gambar nya tidak sesuai (yakni gambar yang memanjang / atas-bawah) jadi dari sini tau kalau styling yang saya buat lebih cocok ke gambar yang kotak / melebar.

apa mas @oonid bisa mengganti gambar yang memanjang tsb menjadi melebar? atau perlu dibantu? :smile:

[oonid]

ok mas Ridho, I will try to make the image to be square, later.

mas @ridhof I have resized the image of bu Inge, now it's square. please test again, and merge if it is done. thank you.
