I'm getting HTTPS 500 error when I try to upload photos (Error :"No JPEG support in this PHP build")

Right, I tested the issue on a few testing accounts and I couldn’t reproduce the issue there, but it seems that this issue still affects some accounts/servers. I’ll have someone look into this.

Meanwhile, I created an outage topic about it where I will share updates about this issue: PNG and JPEG support missing for GD extension on some accounts
