Create wallet offline like Bitcoin? Signing transactions offline?

Can I create a wallet offline with the Peercoin client? Would I then just backup the wallet.dat to a secure location?
Also, is there a Peercoin wallet similar to Electrum which has the feature to sign transactions offline? I'm looking for ways to send PTC without having to import the private key, or transferring the wallet.dat, onto a computer with an internet connection.
Security tips would be great!

Question immortalizing Art on the Blockchain Network

Hey everyone o/
I recently stumbled upon a post of Andreas showing that there was a bitcoin signed transaction with a bunch of kitties on it. After doing some research, I found out, that with https://cryptograffiti.info you can put some rather small images on the blockchain as a signed transaction.
I have made a few abstract high resolution renderings, showing abstract, colorful forms of things and I would like to sell these digitally with a certain proof of ownership. The Bitcoin Blockchain would be a good place to put those images and send them to the new recipient.
Here's my question: Is there a way to permantly store the ownership of these pictures on the bitcoin blockchain? These pictures are hundreds of Megabytes big, so it would not fit on a single block at all. Is there a better way to store the ownership of the pictures permanently decentralized online?

tl,dr: how to put big pics on bitcoin Blockchain as a signed transaction, so you know who the owner is?

Thanks :*

How to check if a bitcoin transaction is correctly signed?

I would like a generic solution to the problem of verifying that a raw transaction is correctly signed. Normally, one can just use bitcoin-cli testmempoolaccept and if the answer is true, the transaction is fit to enter the mempool (and therefore correctly signed).
However, this only works for new transactions to be included in the blockchain, I would like a more generic solution that works for already confirmed transactions and transactions that might spend transactions not yet in the mempool.
With some work I think I could come up with some validation method for P2PKH transactions. For example, for this transaction, I could use something like bitcoin-cli verifymessage 1LBCr8dpZV3fSj3ha1DihMHSvqR3S53jLN , where rawTx can be obtained by bitcoin-cli getrawtransaction and signature from the scriptSig field of the decoded raw transaction. However, this only works for P2PKH transactions. There are probably ways to adapt this to P2SH and segwit outputs but this seems a lot of work to do for every scenario (with different sighash values etc). Isn't there a set of bitcoin-cli commands or some code snippet out there that does this already? Some kind of command that reverses/verifies the output of bitcoin-cli signrawtransactionwithwallet .
