Never put two 468×60 banners immediately next to each other — they compete and cancel each other out. Banners with free offers that are related to the site theme work very well.
I think a primary focus of the main page should be to promote the other sections of your site. You should probably try to work that into the layout.
Yes, I will be putting an alt tag on my image today, thanks for that tip!. I will also be changing the two banners and placing only one on the main page. I am currently working on my slot machine reviews and I plan on getting rid of the “Free Games” section and replace it with the slot machine reviews. After that is completed, I will throw up an article section that pertains to slots. This whole venture is definitly a lot of work, more than I planned on doing. But it is actually a very enjoyable challange and I am definitly learning alot, more than I thought I would. Thanks of your feedback, it is very helpful.
