@Alb3c Thanks for your report!
May we ask which version of IRIS you're using? If this is version 2.0.0-beta-1, this will be fixed in beta-2.

I can confirm that this is issue remains in version beta-2. It seems that the docx-generator 'image_handler' feature was added to dfir-iris/docx-generator in #1, but it hasn't been merged into its master branch at this time.

I was able to resolve this by building a wheel package for docx-generator from develop and replacing the extant package in source/dependencies.

I expect that this will be handled before this moves out of beta, but I'd be happy to submit a PR, if you'd like.

Thanks!

Hi Tommy @tobraha,

Thanks for pinning the issue! Indeed, the replacement of the updated wheel wasn't done yet. We're updating for the beta-3 👍

Cheers
