How long does it take to get a tourist visa approved, and does anyone know how to upload your passport photo onto the Thai e-visa website?

Hi, I want to apply for the Thailand Pass but I’m trying to figure out how to upload the passport photo and the Passport info page. Do I just take a picture of the passport and photo with my phone? How do I get the files onto the computer so I can then drag and drop or whatever? I guess I’m not tech savvy! 😭 I would be grateful for any help! TYIA.
