Welcome to CS jupiterwolf, I hope you'll like it here^^.
Which pictures do you mean, the oekaki ones? If you mean the oekaki there is an excellent
"How To Use Oekaki?" Guide that explains all the different tools and functions.
If you havent already, you might want to check out these topics for new players:
Also, have a look in the
CS Help section and the
Guide Index, you can find all sorts of useful links there!
If you have any questions, me and everyone with a pink name are
general helpers (full list of names
