Hi Alchemy,
Thanks for contacting Syncfusion Support.
Currently, we have support to bind CarouselItem's image only from Resource folder, as we are providing only the image names that will get the images from the Resource folder. We have implemented support for providing custom views to CarouselItem and with that you can define your own paths and can achieve your requirements. This implementation will be available in our upcoming Volume 2 release. You may also check our website periodically to know about our release schedule.
Regards,
Hemalatha M.R.
