Image Question

Hello,

Question 1: How do I link an image so when it appears on my index page and someone clicks the image it goes to the article instead of a blank page with the image on it?

Question 2: Is there anyway that I can prevent the images on the index page from becoming so huge? The image isn’t that big in the actual blog post but when it appears on the homepage (index) in the first two spots it is very large.

Here is my site: http://www.disneypinsblog.com

Thanks for your help!
