Hi guys, for the jetton metadata standard, what goes in the "image_data" field?
I used a base64 string of my svg logo but it does not render on Tonviewer.

Base64 of PNG or WEBP worked fine.

neither png nor webp works for me. logo doesnt render on tonviewer. do i need to refresh the metadata or something like on opensea

I used a URL to the image like this:

https://app.hipo.finance/hton.png

Source: https://github.com/HipoFinance/contract/blob/main/scripts/deployTreasury.ts#L55

this is my metadata uri: https://ipfs.io/ipfs/QmQJ6cbf49po4QMuucZoDgW6iUeX59Mzh7Atz4j8sWT5yp

tonviewer manages to read all the fields except image

I haven't used the metadata uri approach. So your way differs from mine.

Isn't it a caching problem? Maybe you have used an older uri previously and now changed it, but tonviewer cached it?

I had a similar issue with Tonkeeper, and images where cached. I managed to change the URL a little (by adding a ?v=1 at the end) to bypass the cache.
