[Plugin: NextGEN Gallery] Huge numbers of images – performance problems?

    Hi

    My question is about potential performance issues for NextGen Gallery or WordPress when galleries contain hundreds of images.

    I have been asked to make a website for a photographer who wants to upload every single image from a photoshoot into a gallery. Each gallery could have up to 800 to 900 photos in it. There will be up to about 20 galleries online at any one time.

    Each image file will be max 150Kb. They will upload them as zip files, approx 10 per gallery, each zip file ~9Mb.

    I know they will need a lot of disk space, and the PHP file upload size limit will need to be increased to handle the zip files.

    I’m wondering if you think having so many images in a gallery is likely to cause any performance problems for NextGen Gallery and/or WordPress? I’m thinking specifically in terms of database queries, memory usage, server load etc. Either for the display on the actual website or for the admin screens. The gallery pages will display small thumbnails (~20k), but multiplied by 900 that’s a lot of data!

    Traffic will be low as the galleries are password-protected so only the customer can see it.

    Any advice you have before I say ‘yes’ to them is very much appreciated…

  • I must fairly say that I never thought about such a amount of images, i know that some parts need to be optimzed for such a case (selection of preview image, selection of singlepic in TinyMCE etc.)

    Hi,

    My website contains 70+ albums, and some of those albums have more than 3000+ pics! each pic is about 200kb.

    Till now i have none performance problems at all!
    using the latest version of wordpress and ngg.

    site is running on a dedicated server, and is the only site on it.

    Thanks very much for both replies.

    alexrabe: We won’t be using a gallery preview pic, the tinymce button, or singlepic, so they shouldn’t be an issue.

    gasjeerbij: Wow, makes my requirements seem small in comparison! Glad to hear you haven’t had any problems.

    I’ve since realised that the ‘Upload Images’ tab allows you to select multiple images in one go, so there’s no need after all to upload massive zip files, which removes that problem. I did a test where I uploaded over 200 images in one go and it worked like a dream.

    The photographer has also now agreed that she is happy to split each photoshoot over multiple galleries, so each will ‘only’ have about 2-300 pics. We calculated that the page load time for 900 images is about 5mins (on fast broadband), and most people just won’t wait that long.

    Many thanks

    If you have a heap of images to show in your blog as albums, it is a better idea not to host them in your own server but use Picasaweb albums and Flickr repositories and pull them to show on your blog. There are very good, reliable and feature-rich plugins available which would do the job for you. They use the Flickr and Picasaweb APIs and serve the pictures on your blog.

    S.K

    Is there a way to integrate Flickr with NGG?
