    i set up a gallery but the thumbnails are shown with the original imagesize. i tested every gallery layout.

    do i have to install any additional plugin or something?

    my wordpress is freshly installed and the first thing i did was installing the awesome flashlight theme!

    great work btw!




    If wordpress doesn’t resize any thumbnails the gd-image libary is not installed on your server (or your hoster deactivated or restricted the usage of/access to this libary). Please ask your hoster to activate/install the gd image libary and afterwards regenerate the thumbnails with: again. An interesting article about this issue can be found here:


    Thank you for the hint.

    I checked it and GD seems to be running.

    GD Support enabled

    GD Version bundled (2.0.34 compatible)

    FreeType Support enabled

    FreeType Linkage with freetype

    FreeType Version 2.2.1

    GIF Read Support enabled

    GIF Create Support enabled

    JPG Support enabled

    PNG Support enabled

    WBMP Support enabled

    XBM Support enabled

    What now? :(


    Anybody have an idea?


    Do you get any error message when you try to regenerate the thumbnails with: ? Can you post a link please?


    Yes, but i find out that something has a problem with big image resolutions. i used a res e.g. 2363 × 1269. this seems to be too big. with lower res e.g. 1000 x XXX everything is fine. i didn’t find out from what resolution this problem appears.

    i hope this can fixed soon. or is that a limitation by GD library?


    We use WPs internal thumbnail/resize function to generate all images: – I’ll do some research but it sounds like a wp limitation.



    I have changed the Blog-display like desrcibed here:

    to show the full content, like images in the blog.

    So If I want to Change the Imagesize in the blog-preview (make thumbs size smaller) did I have to change something in the function.php or via css.


    If the images are embed in the content itself you need to change the media settings (Settings > Media) because WP controls the thumbnail sizes here. Otherwise you need to change the dimensions in functions.php.
