>Subject: [PATCH] Bug 35558: Do not retrieve the local image if none exists
>
>On the search results we are fetching the thumbnails of the local cover
>images using catalogue/image.pl
>Which means 1 GET per results on the page.
>
>This patch suggests to have this information beforehand in order to
>reduce the number of hits and network traffic?
>
>However the page load will be slightly slower ofc.
