Assignment thumbnail name to original file name

Henri

Hello,

is there a simple mapping from the real file names to the names of the generated thumbnails?
We also store the file names in a database when uploading to files.gallery and would also like to store the file name of the thumbnail.
But this can't happen immediately, because at the moment of the upload there is no thumbnail yet.
Therefore the question about the assignment of filename to thumbnail.

Thanks a lot
Greetings Henri

Henri This is the function in index.php that generates the resized image file name:

function get_image_cache_path($path, $image_resize_dimensions, $filesize, $filemtime){
  return config::$cache_path . '/images/' . substr(md5($path), 0, 6) . '.' . $filesize . '.' . $filemtime . '.' . $image_resize_dimensions . '.jpg';
}

This might change in a future release if there are more effective ways to store the file.

Henri

Thank you very much,

I think we can solve our problem with this.

Hi, I understand correctly, can you add the name of the thumbnail file with the name of the original file? maybe the name of the folder could be included?
for example, there is asd.jpg in the test1 folder, would it be possible to generate a thumbnail as test1.asd.jpg.somefilemtime.jpg?

Karl

David Sorry, but I'm not quite sure what you mean by this. Files Gallery will automatically create thumbnails for images. You want to create custom thumbnails for each image? This is incredibly tedious.

David

I would like to solve the cleaning somehow, if I remove a folder, the thumbnails are not deleted, but if the name of the thumbnail included the name of the folder and the name of the file, then I could delete the unnecessary files with a simple command

Karl

David Ok, I get what you are asking, although this should be a separate topic.

Cache currently uses md5() encoding to encode the full image path into a file name. It has been considered storing full image paths in cache, like _files/cache/images/path/to/image.320.jpg, but this requires creating nodes on server for each folder, and is potentially insecure. I might consider this for a future release.

You know you can just delete the entire image cache once in a while? It will just recreate cache for existing images.

David

yes, I delete it from time to time, but with many folders it takes a long time to go through each folder and generate the thumbnails.
I also know the files.tasks.php solution, but it doesn't work properly for me, it generates files, but not the right ones

Karl

David yes, I delete it from time to time, but with many folders it takes a long time to go through each folder and generate the thumbnails.

Understood. But do you need to pre-create all thumbnails? I would't personally do that, since creating resized images from medium-size images is normally very fast on modern servers anyway.

David I also know the files.tasks.php solution, but it doesn't work properly for me, it generates files, but not the right ones

This would have to be diagnosed in a separate post.
