How do I make hearts using HTLM?

Here's a good page on inserting an image in HTML on a web page. Basically, the image needs to be uploaded to the server (often they're placed in a directory named "images" or the like on the server).

You're going to have to find or make an image of a heart. You don't make images in HTML. If you Google "clip art hearts" you'll find there are plenty of free heart images out there that you can download & use. Here's an example.

There's actually a way to "code" a heart without uploading an image.

Use the following:
♥

For example: I ♥ dogs
