Kol Hakavod to Yitchak Sultan for putting up this picture, but doesn't anyone think it's a little misleading? After all, this page is about the Halachic Challah one must separate from dough...I know there's no good picture for that, but maybe no picture is better than a misleadng picture?

I agree that it is a bit misleading. See the new picture.
Regarding the issue of making Challah with the shiur Challah and then freezing some of it and baking it in amounts that aren't the shiur Challah, I heard Rav Hershel Schachter (Brachot Shiur 71 mid-shiur 5778) rule that one can recite the bracha since it is one person kneading it and it is only separated for himself and not separated for other people. Even though it is against Tosfot Brachot 38b we follow the other poskim.
