View Full Version : Thumbnail Viewer and Iframes

05-16-2008, 07:32 PM
Hello to all! I am new, a little special and very aware of it. my question is this:

How can I use the Thumbnail viewer to display an Iframe w/scrollbar on mouseover and then have the iframe replaced when I mouseover the next thumbnail to display an image?

Here is a link to a sample of the page I am building:


Here is the code I have attempted to modify:

var dynimages=new Array()

//Set scrolling for text content if text content used("yes" or "no"):

//Set optional link target to be added to all images with a link:

ok ... when you follow the link to the sample page ... now it is working ... I am very greatful yet extremely confused ... can someone please explain why it is working now that it is live but not when I try to preview in browser through dreamweaver?

Most if not all versions of DW are for designing HTML and/or simple javascript only. You should never abandon a script because it doesn't work in a WYSIWYG editor like DW or FP. In fact, complex scripts are best added to a page using a text only editor like NotePad or one of the many advanced text only editors developed for web design. Pages should be tested in the browser, not the editor. If IE is your browser, it will often give an advisory/warning when viewing scripts locally. This generally will not happen once the page is live.

thank you for explaining that ... i really am a newbie :) and by the way thank you for the modifications you made to allow the iframe to work within the thumbnail viewer. I really like the way it looks and functions on the page.
