I renewed online for me n my wife,
took picture ourselves using smartphone at home,
save in RAW file.
take several shot better.
at first upload always failed, after a while OK and accepted.
after submit, next day morning ady got result accepted or rejected.
only my wife need to reupload coz she wearing tudung got shadow on forehead.
so retake picture with extra lighting n different style of tudung, less shadow.
finally accepted.
now waiting for pickup, we chose to pick at wife's hometown since rural areas not so much ppl.

bigger than 1mb,
i upload 8mb one oso fine.
