Sorry about the delay in replying to some of your comments. Turns out the software use for this site stopped flagging new comments. This means I didn’t see them! You gotta love tech.
First, The issues about images. Take a look at this link background
The issue here is structure. So, let’s talk about it. Take a look at this.
Web pages have a structure. You text talks about it on page 9. Web page structure is broken down like this: Elements, Tags, and Attributes.
Know them, code them, love them.
Several of you have had trouble looking things up in you text because you were looking for tags when needed to looking at attributes. Kinda like telling you doctor that your leg hurts when you have a pain in your big toe. You need to be a little more exact.
Take a look at the link and see if sheds some light.
