Blog page

Hi there, I have two questions concerning my blog page: 1) How can I remove the "Category Archives: Spinsels" part from my blog page? 2) How can I edit the post's "introduction" shown on this page so that it will contain the first paragraph (and preferably the post's image too) instead of merely the first one-and-a-half sentence ? http://www.pennenspinsel.nl/category/spinsels/ Thanks in advance!   With kind regards, Tabitha
