Multiple Image download (ZIP) - how to add download:true to a VisualForce page

To enable multiple image download using the zip button, a Visualforce page should be implemented. Using this VF page, one can then modify the abilities accordingly.

After creation of the Visualforce page, the latter can be added on a page layout or on a record page using the Visualforce Lightning Component.

In order to display the zip button, the download:true option should be added before the ability list in the Visualforce page as shown in the code snippet below:

    <apex:page standardController="Opportunity"> 
     <sharinpix:SharinPix height="500px" 
        parameters="{
             'Id': '{!CASESAFEID($CurrentPage.parameters.Id)}', 
             'download': true, 
             'abilities':{'{!CASESAFEID($CurrentPage.parameters.Id)}':
                {'Access': {
                    'image_tag:true,
                    'paste':true,
                    'image_copy':true,
                    'image_download':true,
                    'image_rotate':true,
                    'image_crop':true,
                    'image_delete':true,
                    'image_upload':true,
                    'image_list':true,
                    'see':true }
                }
            }
        }" 
        /> 
    </apex:page>
