Users with viewing rights unable to access attachments

[Nathalie De Vos]

Hi everyone 

We have a page that contains multiple attachments (pdf's and video). 

Users that have editting rights: Can open these attachments and the page looks perfect. 
Users that have viewing rights only: Are unable to open several attachments. 

Could it be that the page is too heavy as there are too many attachments? 
If so, we do needs this content on the page, how would I go about making it lighter without losing the content. 

Thanks in advance
