3. Also can I create an image gallary on a widget? I was able to create the image gallary in my post, but I want my sidebar to have a ongoing slide show of images.

You can't use the WordPress.com Slideshow in a widget, but you can put selected thumbnail images from your site in a sidebar by using a Text widget, the Gallery shortcode and "includes" with the Image ID number. To see an example of this in action, check out the sidebar on any individual post on my photography site (no sidebar on the front page with the theme I'm using).

4. Is there a way to only have my profile picture show up under my Home Page and not on every page?

If you use your profile image in your header (the answer to #1 above), then you could limit it to just your home page by adding ".home" to the CSS selector like this:

.home #branding hgroup {
	background: url(http://1.gravatar.com/avatar/d7efe9da41c104e5328029c5a2366613?s=128&d=identicon&r=G) right no-repeat;
	padding-right: 140px;
}

For the Gravatar widget, I see you already figured out something similar by using the following CSS. Nice work!

.widget_gravatar {
	display:none;
}

.home .widget_gravatar {
	display:block;
}

Can I control different widgets for different pages?

There aren't any built in settings to do this, but you can work around it by using CSS selectors like ".home" just like you did for your Gravatar widget.

There isn't an image gallery widget available right now, but check out this reply for some options:

2. How can I change the font size on my Tag line. I have paid for the upgrade custom and I was able to change the font size for my header but I can't figure out how to change the size on my Tag line.

Here is an example. It includes changing the text shadow so it looks a little better than what comes with the larger site description font size.

#site-description {
	font-size: 20px;
	text-shadow: -1px -1px 2px black;
}

You can change the numbers until it looks good to you.

Note that if you want to make the description line wrap, one way would be to adjust the padding-right value from the last example I sent about putting an image in the header. Try changing that to 340px to see how you might update it.

1. Can I add my profile picture and/or my logo on my header? A small size on the right or left hand corner?

Here is an example showing how to add an image to the right side of the header in the Matala theme:

#branding hgroup {
	background: url(http://1.gravatar.com/avatar/d7efe9da41c104e5328029c5a2366613?s=128&d=identicon&r=G) right no-repeat;
	padding-right: 140px;
}

To customize it, change out the image link and the padding to fit your image.

Thanks for all your help in advance.
