Images Keep Disappearing

[origomedia]

Hi Everyone. I have a problem on my site with images that I have uploaded disappearing after 24 hrs. If you look at this page http://www.millionaireasia-indonesia.com/index.php?option=com_virtuemart&view=category&virtuemart_category_id=8&Itemid=620 you will see that all the images are the same size except the Four Seasons one. I have uploaded the thumbnail and it works for a day or so and then it goes like this. Has anyone got any suggestions? It also happens on this page http://www.millionaireasia-indonesia.com/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=84&virtuemart_category_id=8&Itemid=620 where all the thumbnails are now not the right size.

Would like some suggestions as to why it is doing this after about a day or so as if it carries on it will make my clients very unhappy.

Many thanks Jim

Look like you are using dynamic thumbnail resizing. Turn this off in your vm configuration.
