253: Could not create preview image

You linked an image file with [j]-> or a still image for a media file with [v]-> or [w]->. The Aneamal Translator would normally generate a preview image of the original image and integrate it into the webpage. But the creation of the preview failed. A possible cause is that the original image’s file type is not supported by your PHP installation. Previews can not be generated of images whose width or height is zero either.

Solution

The Aneamal Translator creates preview images with one of two PHP extensions: preferably Imagick or alternatively GD. The GD extension only supports loading few common image formats such as JPEG and PNG; Imagick supports many more.

If you need to create previews from image formats that are less common on the web and do not have Imagick/ImageMagick activated yet, you could install the software or ask your web hosting service to do it for you.

You can also create previews of images with software of your choice yourself. Use the [i] file token instead of [j] to link your own uploaded preview image and the original like this:

[i]->preview.jpg->artwork.qoi

If the error occurred in connection with a still image for the [v] or [w] tokens for integrating video or audio files into the webpage, you can reference the still image by an absolute address instead of a relative address. The Aneamal Translator will not attempt to generate a preview from it then:

[v]->https://example.org/still.jpg->video.mp4
