Save .png + analysis

Please create an area where it is possible to train with .png files + computer analysis.

• Save custom .png files
• Open them anytime and analyze them anytime with engine

That would be a big step.

Do you mean PGN files? (.PNG files are photo files.)

All the games you play here have a PGN file generated after you play.  After a game, just go into your archive, open any game and click "Get PGN" and you and your computer can analyze until the cows come home. As a diamond member, you have access to your whole archive, not just the last 30 days (like basic members).

yes sorry, PGN  I do not mean to analyze games which I have played against opponents. I want to build new games from scratch and save and study them. Is this possible?

That's not possible on site. However, there are a number of database programs that can do that. I use SCIDvsPC.

Thanks. Works on Mac, too.
