I changed my chain and think i cut of too much, now the chain skips on the big chainring when i pedal hard. I had a skipping problem on the cassette a few months ago, and then the solution was to get a new cassette. Is the problem a short chain or a worn front chainring? Still have the links i cut.

You need new chainrings
Definetely not a chain length issue, there are at least 4 links that can be shorten on that chain, IMO. Skipping is usually appearing when components wear differently. New chain won’t mesh properly with worn components, usually its the cassette, but chainrings can skip too.
Chain length looks fine. Chain ring looks very worn.
Worn chainrings + you’re crosschaining. Can’t believe nobody mentioned that.
Check the links where you shortened the chain and make sure they have full mobility like all the other links. Sometimes chains can skip when you link the chain back together but the plates are bound up from putting the pin back in. This causes the chain to not lay completely flat on your cogs/chainring and can cause skipping. If you find a stiff link wiggle the chain side to side at the stiff link pretty vigorously and it should loosen up the plates a little bit to allow the link to move normally. If your chain uses a quick link, it might not be snapped closed all the way which can give you the same issue. To easily close a quick link, position the quick link between your cogs and chainring with the quick link at the top side of your chain. Then squeeze both brakes and put your weight on your cranks and you’ll hear it snap closed.
You’re in a gear you should never be in. That combined with a worn chainring and a new chain is not going to work out well.
The chain is fine, if anything it’s too long.
