I've been looking around for simple replacements for iWeb features that don't work anymore or are compromised by MobileMe closing.
Now that a lot of iWeb users are being forced to learn about FTP, perhaps thay will become more comfortable with uploading assets to the server to take advantage of some of the features that are available to them by using HTML Snippets.
GalleryView is probably about the easiest jQuery slider I have tried - and I've tested quite a few! Entering all the code into the snippet makes it easier to change out or add images to rather than uploading an html file and referencing it in an iframe.
Last night I took a look at the jQuery options for Google maps since there seems to be a fair amount of interest now that the widget is defunct. The one I chose is really easy and all the mods are fairly obvious in the javascript. The demo folder has lots of examples...
