Hi everyone!

Long time developer, but new to Algorand and blockchain - but absolutely loving that I can work with Algorand using languages I’m already familiar with.

I’m sure these may be newb/basic questions - so apologies - but I’ve hit a couple roadblocks and any help would be greatly appreciated.

1. I created an ASA token and pushed it to the TestNet - however, no matter what image I use for the Token Image, AlgoExplorer is defaulting to the default image. The image is in bytes. Does the TestNet not support images or am I doing something wrong?
2. I pushed an ASA Token to TestNet, and then wanted to modify the configuration (changing decimals from 0 to 2). The reconfig transaction went through ([Algorand Transaction](https://testnet.algoexplorer.io/tx/E5KNLBODMIQHM3GNTLVDEJ6JK3VIZ7XZCTSMC3X3S3SWHJTB2HMQ)), but on the main asset page, it is still showing decimals as “0” ([Algorand](https://testnet.algoexplorer.io/asset/43564261)) - where did I go wrong?

Big thanks in advanced!

1. The images [algoexplorer.io](http://algoexplorer.io) displays is manually updated by the company behind [algoexplorer.io](http://algoexplorer.io) when you verify the asset.
2. You cannot change the decimals once the ASA is created. The only fields that can be changed are the 4 addresses (clawback, freeze, manager, reserve).

Note that if you want your asset to be later (in a short-term future) recognized by all platforms, it is highly recommended to follow ARC-3: [ARCs/arc-0003.md at main · algorandfoundation/ARCs · GitHub](https://github.com/algorandfoundation/ARCs/blob/main/ARCs/arc-0003.md)
