Product Images aren't generated

[madeinweb]

hi, i've a problem,

in my site, when i upload a product photo, the system doesn't generate all the type and format of them (field_zoom_default, field_manufacture, category_default, home_default etc.) but only one or two type. The result is that i can see product image in backend, but i can't see the product image on the front end (neither in home page neither in product page) of my shop

what's wrong? ty
