Plugin gets stuck on images at times

Hi,
There are times when it just does not give the DELETE ALL button even after 60 minutes, as it is stuck on some images saying PENDING or ASKING

If it gets stuck for more than 20 minutes, can you just mark the image as used so that the page completes. This is especially important with the PRO version

Thanks
