If the image of your NFT is blank, please check the following steps:
1. Select the blank NFT.

2. Click the NFT, copy the Token ID and contract address.

3. Go to any other NFT's page, substitute the contract and token ID.
Or type in the following url: https://lootex.io/assets/contract address/token ID

4. Get to the page of the NFT and wait for loading.

5. After processing, go back to your own vault and you'll see your NFT.
If the problem still occurs, it could be due to NFT project side not configuring their metadata properly (image/video in the wrong trait_Type). We suggest then to contact directly their customer service.
