Missing alt property on the image

Co-signed on this. We can't use this module without being able to provide alt text for the preview image for accessibility due to federal requirements. Looking into whether it can be added through custom code or whether to use a different module right now, but other than that, this module is great.

Happy to review any patches or MRs. If you're looking for a custom solution you can call \Drupal::service('pdfpreview.generator')->getPdfPreview($file); which you can handle however you like.

is there any progress in this?
