Hi Darlene

I should clarify what I meant about your image tags - the Google algorithm, while not the only one out there, is surely the most 'important' just by virtue of it's sheer volume of users.
Now, the spiders that come to your site want to see image tags that reflect what the image actually represents. So while I definitely encourage you to fill those spaces in with keyword rich info they should also reflect the true nature of the images.
So, with that in mind, I'd suggest changing the ones that say just 'Virtual Assistant' to - for example the 'home' button could read 'D.Victoria Virtual Assistance Home'
(now, that's a little long but is OK for that one...)
For 'about' it could read 'About our virtual assistance services' etc. - you get the idea
Give it another tweak in that respect so Google doesn't penalize you!
