My solution has been to left click , select “inspect element” to open the browsers HTML window.

Then zoom out the generator as far as it goes , and scroll down so the entire image gallery (or a part of it at least) is rendered within the browser.

The ctrl+c copy the HTML and paste it in notepad++ , and use regular expressions to sort out the image prompts (and image source links) from the HTML code

Not exactly a good fix , but it gets the job done at least.
