Content of chained image boxes disappears

I am using RT-18 and I have a problem with the chained image boxes which I have placed on the front static page. I have incerted images 5 times already, and they keep disappearing… I mean - the website is in the process of being made, so naturally I edit this and that, but when I click on the front page template to edit something (not the chained boxes module), the images that I have inserted prevoiusly in the chained boxes module disapper. Like I said, 5 times already, and it is quite frustrating, to say the least. Can anyone help with this, please? Thank you!
