I just figured out the problem. Whenever you upload a photo you need to confirm it in your Hive keychain. My mistake was I opened my splintertalk account in my chrome app where extensions are not allowed so my Hive keychain wasn't popping out for confirmation. I tried in a different browser that allows extensions (and where my Hive keychain is installed) and it worked. I hope this helped someone with a similar problem and a newbie in the platform like me.
