I finally got hold of a great Tech person at WordPress (who identified himself as Charlie C. Thanks Charlie!). Charlie reinstalled my old WordPress Theme called Bueno - then made some adjustments that enlarge the images. Things are still not perfect because Bueno is an outdated Theme, I don't believe it's even offered by WordPress anymore.
At some point I may need to change/update things. But next time I'll be a lot wiser about it and simply check out at other WordPress Blogs first and see what they are using - until I until I find one that fits my requirements. I might have to pay for that, but that's OK as long as it works.
In meantime I'm leave things as they are and we'll get something posted up here.
