Hi,
The carousel was designed to slide all items at once when the "NEXT" or "PREV" is clicked. Other ways, it would called "slider". And we already have an extension which does what you want, which is called: Flexilbe - Fancy Product Slider (can be found in our Extension library). In that extension, sliding all items at once is also non-possible though.
The image that you are saying:
www.flexiblewebdesign.com/say.png?extension=carousel
it is 1x1 transparent image, it shouldn't create any problem in the layout. Is there for our records, it lets us to get the "domain" name where ever our extension is used, and we validate the domain name periodically to see if the extension is legally purchase from us OR downloaded from blogs or forums illegally. (by the way, we collect only domain names, no IP, no history, or no private information, just domain names in the form of
www.domain.com or sub.domain.com)
There is no way to remove it since it is encrypted and embed to all of our extensions. What kind of CSS problems you are having? Can you please provide me your URL and let me check your website. I can't delete that line for you Otherwise the extension becomes unprotected, but i can solve the problem you are facing.
