My workflow for a single image: I go to https://translate.google.com/, click the "Images" button, click "Browse your computer" to choose an image, translate, download the translated image. This works very well for a single image or a small number of images. However now I have a large number of images (50+).
Can I somehow do this in bulk (in batch)? I am asking specifically about graphical in-place translation, which preserves the layout, where the original text is replaced in the image itself.
(One thing I already tried, instead of using images, use a multipage PDF. But Google Translate does not work for scanned PDFs. However it does work for images.)
