How to delete a specific image (ad) and external links on a selection of epubs

[Robert78]

I have some epubs with the same ad on several pages.
I'd like to get rid of them by selecting multiple books and indicating the file name to delete. Once files deleting, I'd like to have an automatic repair task to clean the dead links to the image. At the same time, external links (twitter...) could be also deleted.

today, I can do it manually, book after book and it's very slow :
1) book selection
2) edit book
3) report
4) image selection
5) image deletion
6) check and repair

Is there a way to automate this. Can a plugin do it ?

thanks a lot for your help

You do not need step 3.

What I do is delete all HTML I don't want including the ads, internal ToC, previews, copyright notice, list of the authors other books, reviews of the book, and any other rubbish. Then I check the book using Calibre's error check. I delete any unused graphics as reported. Then I remove unused CSS and Lossless compress the graphics. This fixes the steps you left out. Your way you could end up with HTML that's mostly blank because you got rid of the advert graphics. By deleting the entire HTML, you can then get rid of the graphics no longer used and also have a smaller ePub.

As for automating this, there is no way to do that.

Thanks, it's a cleaner process.
But I takes me less than 30 seconds to remove sometimes the same 20 images without inspecting all the html code, sometimes in tens of sub separate html files and the visual effect is perfect. I'm not patient and html code is difficult to read

For optimal result, I'll consider your process.

HTML is not difficult to read. I suggest you learn HTML/CSS as that will help a lot to make any changes you want in an eBook.

Report is just that. A report with the added benefit of linking.

Deleting the Image there, just leaves a 'broken link' at the usage point.
You could use the Editor and Debug.
Delete the Image: debug: fix the errors that caused: save
