I don't know if you can upload pictures, but I looked it up and you can apparently send up to 1 million messages per account. Unfortunately, I couldn't find the size limit per message, so I'm not sure if you can use that to upload pictures. Also, the nRF Cloud seems to be only for development, so you'd need an alternative for production anyways.

Thank you for such a quick answer and the clarification! Do you know anything about the nRF cloud part as well? Is it customizable enough to upload pictures to their servers?

Well, the nRF9160 is more powerful in all aspects (CPU, RAM, flash) than the nRF52840, so I'm pretty sure you could do that. You might need extra storage if the JPEG image is too large for the built-in flash, but apart from that, it sounds plausible. Just keep in mind, though, that LTE-M has a maximum theoretical data rate of 380 kb/s (so about 100 kb/s in real life), and NB-IoT has even lower data rates.
