Who will help me?
In this case, helping is correcting the code below because it only sends lowercase pictures to the API, less than 10 Kb.
Just do it. Take the picture and send it to API.
But it's amazing, even having a 4 Mb PSRAM, it only sends very small pictures. Alright, the PSRAM is for another purpose but why not leave about 200 Kb free for work?
Anyway...
