depends on the service you / your client is using. If your file is to large you could upload it to satellite.earth's CDN. 1GB cloud storage is about 167 sats. Then just drop the files link into your note and you're set. https://satellite.earth/cdn

Ok I tried to sign up but am I putting in my nostr secret key for my id here or do I generate a new one? Ty for the tip btw! 
Can you log in to be it with nos2x or alby?
I donβt understand the suggestion. I do have a get alby?
You can use Alby or the nos2x extension to hold your nsec then when you want to log in to Nostr based services the log in process is really simple, just click and authorise
That's odd. You should be able to log-on with Alby.
I'm not a fan of pasting private keys into websites.
As suggested by Matt, setup a lightning wallet (Alby, WalletOfSatoshi, nos2x) and authenticate with that. After authenticating you'll be able to buy a few GB of storage to upload your files.
