1. Does RFM support the creation of additional thumbnails apart from the internal ones?

2. Is there a way to let RFM create internal thumbnails subsequently for images that already exist in the content folder i.e. have not been not uploaded by RFM?

1. RFM utilizes jQuery-File-Upload package by Blueimp with a number of modifications, but the thumbnail creation process remained almost original. This means you could refer to Wiki or Stackoverflow questions of the original package. In short you have to play with image_versions configuration option which is defined in the following files:

• BaseUploadHandler.php (base uploader class)
• Local/UploadHandler.php (Local storage uploader class)
• S3/UploadHandler.php (S3 storage uploader class)

Extending the image_versions configuration option with new variants results in new image versions (thumbnails) being created. The way you are going to use new images is up to you completely.

2. Once you open a folder with images, that were manually added, the RFM will create thumbnails automatically for you. In other words RFM creates a thumbnail for image if it's not exists yet.

I'm not sure if this issue is related to JQuery-File-Upload or RFM, but when I add the code below to the constructor of Local/UploadHandler.php the extra image is created in the folder "small", however, its size is not 300 x 200 but 1280 x 960.

        // image small settings
        $this->options['image_versions']['small'] = array(
        		'max_width' => 300,
        		'max_height' => 200
        );

Any ideas why this is?

[hhjung2013]

The solution to the above problem ist to put the settings for your extra small image before the thumbnail settings. For some reason it doesn't work if you put after the thumbnail settings.

        // original image settings
        $this->options['image_versions'] = array(
            '' => array(
                'auto_orient' => $this->storage->config('images.main.autoOrient'),
                'max_width' => $this->storage->config('images.main.maxWidth'),
                'max_height' => $this->storage->config('images.main.maxHeight'),
            ),
        );
        
        // image small settings
        if($this->storage->config('images.small.enabled') === true) {
        	$this->options['image_versions']['small'] = array(
        			'max_width' => $this->storage->config('images.small.maxWidth'),
        			'max_height' => $this->storage->config('images.small.maxHeight'),
        	);
        }
        
        // image thumbnail settings
        if($this->storage->config('images.thumbnail.enabled') === true) {
            $this->options['image_versions']['thumbnail'] = array(
                'upload_dir' => $this->model->thumbnail()->getAbsolutePath(),
                'crop' => $this->storage->config('images.thumbnail.crop'),
                'max_width' => $this->storage->config('images.thumbnail.maxWidth'),
                'max_height' => $this->storage->config('images.thumbnail.maxHeight'),
            );
        }

One more thing, is it possible to have RFM delete the additional small images on deletion of the original image just like it does with the internal thumbnails?
