Product image lost on froogle listing

[maxmost]

I submit datafeed to froogle 2-3 times a week, from yesterday, i found there is no real product image close to product link and description, but got 'image not available' instead, this applied to my all products on froogle. Does anybody know where the wrong is?

Another thing confused me is froogle does't list all products in the datafeed, like i have 2000 products in datafeed file, when i searh my store on froogle, the results show only 1950 or 1960, sometimes 1970. I log in froogle acount, and check upload history, it says all products were uploaded successfully. No error occurred.
