 Version 0.90.3 or 0.90.4?  

 90.4 

 Very interesting. Can you choose another server, try to upload and then return to nostr.build to see what happens?  

 Not techy at all, how to do this, and  What are other options? 

 You can also see a list of servers in the Media Servers options in the left drawer.  

 Ah ok, switched to nostrcheck.me and it worked.  Was using nos.lol before.  Should i just leave it set to nostrcheck.me? 

 Ohhh nos.lol is not an image server. That's why it didn't work. 

These servers are all different and each has their own plans to host your data. Chose what fits best to you.  

 Thanks Vitor😊
