Thumbs not working for images with larger upload-size

The CMS Questions

Hi!

For a client’s website I’ve noticed that thumbs are only generated for images which are of an upload-size smaller than ±20mb.

this is what my thumbs config looks like:

'thumbs' => [
    'driver' => 'im',
    'bin' => '/usr/local/bin/convert',
    'interlace' => true,
    'srcsets' => [
        'default' => [
            '300w'  => ['width' => 300],
            '600w'  => ['width' => 600],
            '900w'  => ['width' => 900],
            '1200w' => ['width' => 1200],
            '1800w' => ['width' => 1800]
        ],
        'avif' => [
            '300w'  => ['width' => 300, 'format' => 'avif'],
            '600w'  => ['width' => 600, 'format' => 'avif'],
            '900w'  => ['width' => 900, 'format' => 'avif'],
            '1200w' => ['width' => 1200, 'format' => 'avif'],
            '1800w' => ['width' => 1800, 'format' => 'avif']
        ],
        'webp' => [
            '300w'  => ['width' => 300, 'format' => 'webp'],
            '600w'  => ['width' => 600, 'format' => 'webp'],
            '900w'  => ['width' => 900, 'format' => 'webp'],
            '1200w' => ['width' => 1200, 'format' => 'webp'],
            '1800w' => ['width' => 1800, 'format' => 'webp']
        ],
    ]
]

In my network tab i see this:

Since the client didn’t like the slower page I’ve manually replaced them with smaller images which triggered the thumbs to be smaller… so this made me wonder if this has to do with the upload file-size being to big for the thumbs to be generated? What am I missing here :sweat_smile:

This could well be the case. If the thumb generation failed (which depends on the image, the available system memory…), Kirby 3 fell back to the original image. Kirby 4 instead returns an error to make such issues quicker and easier to spot.

To avoid the generation errors all-together, you can resize the images on upload (but that again is available since Kirby 4).

Sorry, my fault…I was not aware that the repo was on k4… what a simple solution! :slight_smile:
