How to automatically (bulk) insert about 1000 images into 1000 image frames in sequence?

I have about 1000 empty image frames in a document placed across over 80 pages.

Now I want to populate those image frames with images.

I have the image files named in sequential order.

Is there a way to quickly place the images in the empty image frames, in order?

I'll have to do this task every few weeks, so would really love to find a way to not have to do it manually one by one.

I'm aware that you can import multiple images as a batch and then click on the empty frames one by one to insert the images, but that's still kind of one by one. I'm looking for a quicker one-go method, if it exists.

Side note: not sure if it matters but in my specific case the image frames are inserted into text boxes. In other words, I have a large text box on each page. The text boxes are threaded to each other. And instead of text, I have about 1000 image frames inserted into the text boxes that flow from page to page.

Thanks!
