Improve photo rendering performance

[coudot]

When we display a lot of photos, it takes a long time because each photo is recreated on server side.

We could instead return the raw value and let the browser display it:

$lil = base64_encode($entry[$i]["jpegphoto"][0]);
echo '<img src="data:image/jpeg;base64,'.$lil.'"/>';

ANd if photo is stored on disk, we could simply use it as source.

I think this problem occurs on panel: organization chart with photographs.

Indeed, when loading this panel with 5000 users:

• the page takes a very long time to render
• the page is quite slow, even after rendering
• the page display too much result to be usable
• the page send 5000 requests for getting every photo.

Sending directly the raw image cannot solve all these problems.

I think we should either truncate the number of results, or better to have a pagination API, and a filter field on the browser.
