I can log in Nostr.build and I did it now. But my problem is uploading pic in nostr.build server on Amethyst

I checked the logs and do not see you trying to upload, only trying to login. If you need to use a web interface to upload, please create an account but don’t pay the invoice. Go back to the main page and you should be able to use the web upload. Otherwise, since you already used nostrcheck.me, can you upload the screenshot to it and share with me please
