How many articles you can show in the Carousal?

HI,
I put 7 articles in the Hot Joomla Carousal and seems like only 4 shows? How can I have it show 7 articles or images? Also once I create a new article it does not show the pages instantly and take couple of hours to show in the main page.
Thanks

See if in settings for carousel, each item is set to visible. Or if there is a space (' ') character in your images filename.
