Here is a higher resolution for you. Does this work!? (Don’t know how it get compromised) 
Discussion
I think it may get compressed upon upload?
Yes. I also tried to upload the HR file separate to nostr:npub1nxy4qpqnld6kmpphjykvx2lqwvxmuxluddwjamm4nc29ds3elyzsm5avr7 nostr:npub137c5pd8gmhhe0njtsgwjgunc5xjr2vmzvglkgqs5sjeh972gqqxqjak37w of 48 mb and one of 22 MB and got an error.
But here is HR on Nostrcheck from nostr:npub138s5hey76qrnm2pmv7p8nnffhfddsm8sqzm285dyc0wy4f8a6qkqtzx624
But still compressed. What is normal. So I can send only the HR via. Dtan?
Mmm don’t know how to get you the HR via Nostr 😅 without compression. For my clients I always use WeTransfer
You could probably try satellite.earth's AWS but probably no different to what you're using already. Nvm, I'd appreciate a high res version once it's final. Thinking about getting it printed.
Nostr.build should keep the HR when I direct upload it to my account (because its just AWS) but got an error. ‘Upload failed’ nostr:npub137c5pd8gmhhe0njtsgwjgunc5xjr2vmzvglkgqs5sjeh972gqqxqjak37w
What is the resolution of the file?
The .jpg is 48 mb, the .PNG is 22,1 MB
Not the file size, resolution. 🐶🐾🫡
Sorry that is for the JPG 28940 x 20460 pixels 🤣 Its a big artwork 😅
Ok, there in lies the problem. Since the main purpose of NB is to share media for display (not printing) we are limiting how big of the resolution we can handle. This exceeds the limit. If there is a demand, I can implement upload/share with 0 modifications and optimization, but so far you are the first one to hit the limit. 🐶🐾🫡
Yeah I understand its not made for what I do🤣 What should you suggest to use to send HR files to Nostr pleb? I only know wetransfer
satellite.earth 🐶🐾🫡
So this works:
I can see this on Damus and probably browser will handle it with no issues 🐶🐾🫡
Lol JPG not but the 150 dpi PNG file works nostr:npub1de6l09erjl9r990q7n9ql0rwh8x8n059ht7a267n0q3qe28wua8q20q0sd 
Resolution 150 dpi (PNG) the JPG was 300 DPI the format I print 😅 so I know not good for web. But nostr:npub1de6l09erjl9r990q7n9ql0rwh8x8n059ht7a267n0q3qe28wua8q20q0sd like to have a HR file. And don’t know ho to get it to him on Nostr. Maybe we need a Nostr Wetransfer. I saw DTAN (Torrent) but didn’t understand it as normie🤣
