slideshow jumps

Hello – I am a new word press user.

I have been trying to make a website for my artwork using the modularity lite theme from graph paper press. the home page has a slideshow at the top. however, I have noticed that since i installed the cumulus tag cloud, the slideshow briefly shows my first image and half of the second image while loading. once the page is loaded, the slideshow seems to sort itself out.

you can see what I mean at arran3d.com

i was wondering how can i resolve this issue. help!

thanks. 🙂
