There are known issues (which are currently being investigated) whereby flickering can occur in Chrome if the gallery is either loaded into an iframe or hosted on Dropbox rather than on a regular web server.
However, your gallery is not hosted on Dropbox and is embedded directly in your web page.
I have viewed your gallery in Chrome 33 (and Firefox 28.0, IE11, Safari 5.1.7 and Opera 19.0) on my PC and do not see any flickering during image transitions at all in any browser.
Here are a few things to check and try:
(1) Try clearing your browser's cache before reloading your gallery's web page to see if this makes a difference.
(2) Try fixing the HTML errors on your web page.
You can check the code on your web page with the W3C Markup Validation Service and then fix the errors that are reported.
(There is a closing </p> tag on your web page with no matching opening <p> tag.)
(3) Try viewing your gallery on its own web page (rather than embedded in your main web page) to see if the flickering still occurs (to see if there is perhaps a conflict with some CSS or JavaScript code on your main web page): http://www.paradiseblue.com/gallery1/
If none of the above helps , then please post back and let me know what operating system and version number do you use. It might give us a clue to the source of the problem.
