title: Trying to understand custom fields in WordPress
body: <p>I'm trying to make my single.php page show more details about each project/item in a portfolio, with multiple larger image files that will display with captions to the right of the project description.</p>
  
  <p>I'm thinking the best way to approach this would be to use the 'featured image' for the thumbnail display on the homepage which seems to be working now, but I've been trying to figure out Custom Fields to use for my other images (image1, image2, image3). I can't figure it out. </p>
  
  <p>I go to "Enter new" under Custom Fields from the admin screen, enter image1 for the name. What goes in the Value field? How do I get it to work? I know I need to add some code to my single.php page... but what? And when/where do I upload the images themselves? </p>
  
  <p>Any help would be greatly appreciated! I'm a little dense in the PHP department...</p>
