Bug: can't display images in epub

As title. Win11, onlyoffice 9.4.0.

All image type include PNG, SVG, JPEG, GIF, WebP, AVIF, BMP, TIFF, embedded **SVG inline, HTML img tag, Mermaid graph, remote URL img.
They all showed a blank 0.85*0.85 sqcm square.

I’m not sure if previous version can display images in epub normally.**

Another epub related bug. Same Win11, onlyoffice 9.4.0
When I click on a specific chapter in the table of contents, it does not jump to that chapter. Hovering over it shows a “***.xhtml” link. Clicking without Ctrl does nothing. Clicking with Ctrl + click shows a security warning popup about a potentially dangerous link. At this point, clicking either Yes or No to proceed does nothing, and it still doesn’t jump to the chapter.

Hi, @john371911

Thanks for the detailed report.

Regarding the missing images in EPUB — this is a known issue on our end, already registered in our internal tracker. We’ve added your report to it. We don’t have an ETA for the fix at this stage, but we’ll post an update in this thread as soon as we have any news.

Regarding the table of contents navigation issue — could you please send us the EPUB file that reproduces this so we can investigate the exact cause on our side?

@matrix It is .epub actually, but this website limits the upload file type, so I directly edited it.

Hello, @john371911

We have released ONLYOFFICE version 10.0.

Both issues reported in this thread—missing images when opening EPUB files and table of contents links not navigating to the corresponding chapters—have been fixed in this version. Please update ONLYOFFICE Desktop Editors to the latest version to get the fixes.

Please check whether images display correctly and table of contents links work as expected after the update, and let us know the results.
