iweb image hyperlinks not working across pages
I KNOW there are many other threads on this topic, but I can't figure it out!
I am using images as my website navigation and they have stopped working on some pages when I updated it (and won't work no matter how many times I replace them or send them forward/back and republish). I have read some other threads that say it may be hidden objects blocking the links or that the images are in the navigation layer, but I don't think that's the problem (correct me if I'm wrong). I've also disabled the navigation menu since the problem happened, but that was not the cause.
Here is my website home page (all the links are working on this page): http://melissabloom.com/mb/Home.html
but then on this page, for instance, none of them work: http://melissabloom.com/mb/Portfolio.html
To specify I am talking about the "home, about, contact, portfolio and reel" images/links. They are not working on the "portfolio" and "reel" pages and also, the four pages "portfolio" takes you to.
Let me know if you need more info. I appreciate any advice, thanks!
