I’m trying this out in EverWeb but am struggling to make it behave properly – I don’t seem to be able to get it to open up the site in a browser to preview it to test whether it’s working.
In theory, you should be able to do the following (assuming you’ve only got one gallery/slideshow per page):
Go to the Inspector and in the Page Settings section scroll down to Head Code
Paste the code from the code section of the Exhibeo Export page into the Head Code field
Draw an HTML Snippet widget on the page and double click on it
Paste the code from the code section of the Exhibeo Export page into the HTML code in the Inspector
Now this is the bit I’m unsure of, but you need to get the output folders onto your server/ into the published folder so they’re sitting alongside the page you’re editing. It looks like you can only upload to EverWeb’s servers so I can’t actually test this out for you – you’d need to get in touch with EverWeb support to find out how to go about doing this.
