What does it mean if there are more than one incoming addresses on a transaction? How do I know which one sent it?

 have a look at the Bitcoin wiki on Transactions : https://en.bitcoin.it/wiki/Transactions

What you're saying is that the bitcoins were sent from the 1M23... address?
Yes, if you received the 13.+ BTC.

If so, what is the 14SX... address?
It's probably also an address of the sender. A user can generate addresses for every payment he requests (to be able to see who sent him coins). The 14SX might be one of these. With every payment a new address for sending is generated in the background. This sending address is usually not known to the user. So a wallet has many addresses.

Using bitcoind on linux? Try this:
bitcoind decoderawtransaction `bitcoind getrawtransaction f289f1ed2a1f92f897469245b69ba1000ad069c0133e8f85c45c19486a2fed88`

Okay, so in this transaction:

https://blockchain.info/tx/7a516f90c60413454f46650272beb27f131d470b9a338d4d73fa677cf2b33e39

It shows bitcoin coming in from 14SXKWEYtm4BFBftTqe3ZmExT5cJxVb8Z3

and being paid to:

14uBMWG13g6A3yKF9nho7KeLJ8dGa6xQYG for 13.5ish BTC
1M238zbAby4uBbkZ6Sv874bsw28jeg99zU for some change

Probably they are both addresses of the sender, but not necessarily the address he used to send coins. These are addresses with which the sender received coins. Their sum is used to send the amount which is needed to send a payment. If you like to know which address was used to send coins to you, look at the output side (vout) of the transaction. There are usually two addresses. One is yours and the other is the senders (used to pay back the amount the sum of inputs exceeding the desired payment).
