Here is a way that might be useful if it its just some colors/shapes you want.
What all you will need:- I-Frame - behind the photo area; sized and centered where you want the "picture frame" to display.
- HTML page for your "photo frames"(ex. name for this page: photosFrame1Set1)
- Text link or Colored shapes (or thumbnail image etc...) for each choice
Place an I-Frame behind the "gallery" photo or area and in the options dialog for the IFrame, give it an easy name to remember(something that's short and also describes where it is...like the page it's on)ex.:
the page is "photos.html" so why not: photosFrame1 (this way more advanced techniques to update the colors/shapes used for that gallery/area will be easier to accomplish/refferrence)
set the URL of the IFrame to url of the html page with your desired colors/shapes: ex.
http://www.lostdutchmanaz.com/photosFrame1Set1.html
make sure to UNCHECK show border and the scrollbar...in other words neither should show at all.
Now for the page with the different "photo frames."
***Start a new page in BV and make sure to UNCHECK "Center in browser" in "Page Properties"***
Start at the top left of the page and add your shape/image and make sure you make it the EXACT SAME SIZE or a pixel smaller than the size of the IFrame you made for it on the photos.html page.**when you got it the right size...with the shape/image selected..press the up arrow a couple times and the left arrow a couple times...this makes sure the shape/image is at the (x,y) coordinates of (0,0). resize the shape again if needed.
now that you have the first one in place...lock it in place! lol
Next select Insert>Bookmark from the menu or the bookmark icon from the toolbar and click and drag to cover and match the shape/image.Double-click for the bookmark's dialog box and name it something very short(ex. if you used a blue square, name it blue)
Repeat these two steps with each shape/image + Bookmark you want to use for your "photo frame" choices. Each one you will place directly beneath the one before it down the left side of the page making sure not to overlap or size bigger than the Iframe.
Give each bookmark a unique name(no two the same)
***As long as your Bookmark/shape is the same size as the IFrame...all will work seamlessly, otherwise ...some adjustments MIGHT be needed, maybe.****
save and publish the page and return to the photos.html page with the I-Frame and Gallery Photo
Now all you have to do to make the shapes change in the Iframe behind the photo is to link the TEXT LINKS or small images to the bookmark of the selection you want to see.
Okay, say that you made the one page with all your choices using colored squares: blue, green, orange...(you named your bookmarks for these as: blue, green, orange). The first thing you will see behind the photo when you load the page will be the blue square.
to change it to the green square you would create a link to the url and bookmark of it in this format: pageURL#bookmark name
this is what you put as the url of the link you use for that choice, whether it be a Text link "Green" or a small green square hyperlinked using the URL above.
*****SET THE "TARGET" of the link to the name of the I-Frame you created by TYPING it where it says "Target" instead of using the drop down list...ex.: photosFrame1
this way, when someone clicks on the little green square, the bookmark "green" on the page "photosFrame1Set1.html" will be showing in the I-Frame "photosFrame1" on your "photos.html" page behind the picture.
Tada!!
here is somewhat of an example to what I mean...the first is the page i used with bookmarks and the secon is sort of like a viewer or GUI to change to each one:
I hope can give you some insight as to what you are trying to accomplish.
