paps image load problem on firefox

[DANYEYI]

hi there,

 

i have a really big problem that is stopping me from listing all of my items, i have installed the product attribute pictures v4 plus contribution and everything was working fine until i viewed the product in firefox. it appears that if i add more than 4 thumbnails some of the thumbs do not load (refreshing the page makes different ones dissapear), take a look at my test listing here (with firefox) to get an idea of what i mean:

i have tried everything but still no joy! It appears fine in safari and IE so i have no idea what the problem is.

 

any help is really appreachiated.

 

thanks in advance
