Now you're talking about rendering them, which is a different topic than
mounting a resource which serves said images.
You'll only need to mount a single shared resource which serves all the
images. However, given the amount of images you can consider allowing
your front-end (e.g. apache httd) or a dedicated webserver serve the images.
Since you mention that the amount of images can be potentially large
(>250), I'd suggest removing the "show all" option, or using an ajax
viewport (max 20-50 images on-screen at a time, when the user scrolls
you load new images over ajax).
Someone else just suggested storing images in the database. While there
is usually heated debate about this topic (files on disk vs in the
database), let me just say that simply having lots of images is no
reason to move images into the database. For starters, you can always
store your files in a hashed folder structure, e.g. when the ID is 1234,
store the image in a file/folder called /1/2/3/4.jpg

Imagine this situation: users have accounts on photo album where they upload
images. System from uploaded images create thumbnails. Users can browse
their photo - there is combo "show 25", "show 50"... "show all" images. On
page
I render thumbnails on a page which are shadowbox clickable images.
All images ("show all") I do in way described below.
Works fine but in extreme situation there is user with more than 3.000
images
in one photoalbum.
Or -how to do it better way?
Thanks,

Subject: Re: mountSharedResource() on huge amount of images
The general idea is to mount a single handler, which takes
the filename from the url.
There is no reason to mount all images by such a handler one-by-one.

Hi all,
what is the recommended way to mount huge amount of an images
(thousands) in app? Does mountSharedResource() has any bottleneck?
Simplified code look
like:
Folder folder = ((Start) Application.get()).getUploadFolder();
File[] files = folder.getFiles();
List<File> lList = Arrays.asList(files);
Collections.sort(lList); int
i = 0; Iterator<File> iterator = lList.iterator();
while(iterator.hasNext())
{
iterator.next();
String fileName = lList.get(i).getName();
mountSharedResource("/images/" + fileName, new
ResourceReference(Images.class, fileName).getSharedResourceKey());
i++;
}
But what if in folder is for example 100.000 photos?
Thanks for pointing,
