Again, your images are not optimized.

The image on the top is 3000x900, and you simply shrank it to 636x141. Resizing it using what ever you're using to make your web site does not work. You're still loading a HUGE image. http://www.shrinkpictures.com might help If you have Photoshop..that's even better.

I'm browsing and noticing that all of your images are full resolution.

"Heating & Lighting NOT included, but it is anOPTION"

Here's a quick solution. You need to use a program or that web site I gave you and optimize your thumbnails for quick loading. Then, just like you do any link, you link the picture to the full size image. When they click the thumbnail, it goes to the larger image...and when people willingly click to a large image, they're usually willing to wait...but won't wait on 10 large images to load.

I think you're making progress. Web design isn't easy.
