Hi.
A few questions:
(a) Is there any erratic problems detected, with the images,
(b) How many pages are to be checked?
(c) Is this a CMS based website (Wordpress / Joomla / etc)?
(d) Also, what do you mean by "manuel skills"?
I'd probably start with checking whether there's any failures / warnings /errors in loading each images. So I may need a complete sitemap of your pages. Hopefully this is just some invalid link problems, so the fix should be easy. But if it's not then perhaps some examinations into server scripts is needed.
Kindly let me know.
