O/H paragasu ??????:
i am planning to create a web photo gallery. i know there is a lot
available out there,
but i really want to create my own. the problem is not about creating
the photo gallery.
i want it to be scalable.
the plan is saving the image metadata in the database and keep the
original files
in a folder. while it work perfectly, i afraid how many files 1
directory can keep.
in 1 year, there going to be more than 1000 photo uploaded or more.
sure it bring problem
to maintain thus files.
when i see big2 website out there like friendster, photobucket. the
url for the image change
like
pic-1.domain.com/images/filename.jpg
pic-2.domain.com/images/filename.jpg
etc. they seems to put the image in different subdomain. Just wan't to
ask anyone who
did create a big-big web gallery like this. How did you do it?
thanks
I never did create a big image gallery but I have worked with uploaded
files quite many times. There are many solutions to this so it depends
on what you have and what you are willing to do.
A first solution that I can think of is to separate your images in
categories. Add a field in the database table that describes the image
category and make a directory with the same name. When you query the
database you will get the filename of the image (or something like that)
and you will get the image from this specific directory. If you so many
images that this does not solve this you may add an extra field in the
database and add subcategories and move the files into a subdir
(subcategory) inside the previously mentioned dir (category).
Another solution that is better if you are not willing to categorize the
images is to divide them by date. You may include a date or date-time
field in the database that describes the creation date of the image (or
the upload date if you like) and divide the images into directories per
month or per year or even both. Like making a directory 2008 and add
inside sub-directories like 01,02,03... or Jan,Feb,Mar etc. Now when you
query the database you may find from the creation date the directory
that sores the image and everything is in order. For e.g.
If the date you got from the database is 2008-01-23 and the image name
is image01.jpg then the path would be:
<?php
$date = '2008-01-23';
$fname = 'image01.jpg';
list($year,$month,$day) = split('-',$date);
$file_dir = '/data/images';
$path = $file_dir."/".$year."/".$month."/".$fname;
print $path;
?>
