How we can get minted image details using cardano cli or any other open source tools?

You could use the Koios API:

$ curl -s "https://api.koios.rest/api/v0/asset_info?_asset_policy=43c4b46c9635b3a57c9731de817a20b3d099ee2c7f44a0e2723c4bb6&_asset_name=486570746143617264" | jq

The API also allows to filter the output to only the things you need. There are other API calls to find policy ID and asset name from addresses, accounts, or transactions.
