Issue with jxl image not showing thumbnail in comic archive

[iSams123]

The new version works nicely. However there is a small issue, which I am uncertain of the cause.
Before that, i can view thumbnails of cbz archives zipped from the folder with a bunch of JPEG XL images. Now I can only see the thumbnails if I change to zip archive.

To summarize:

• .cbz / .zip can display thumbnails of popular formats (.jpg, .png , .webp, ...)
• .zip can display thumbnails of jpeg xl image (with the help of jxl-winthumb for Windows)
• .cbz, however, does not show thumbnails of jpeg xl image.

Reproduce:

• Have 2 of the same image in jpg and jxl format.
• Zip each of the image in .zip and .cbz archive (4 archives total).

Expectation:

• All archives show thumbnails.

Result:

• Comic archive with image.jxl file inside did not show thumbnail.

Sorry to hear that. I'll investigate. Thank you for the report!

I've attempted to reproduce the issue, without success.

1. Converted a JPG file to JXL.
2. Made ZIP archives of the JPG and JXL files.
3. Copied the ZIP archives to CBZ.
4. Installed jxl_winthumb on Win11 24H2.
5. Viewed the folder in large icon mode with DarkThumbs V2.0

Here are my DarkThumbs settings:

Could you confirm the following:

• Your DarkThumb settings
• Your Windows version
• How you created the CBZ files

It might be necessary to provide a sample CBZ file which is failing.

Thank you for the reply.
It turned out there was a problem with YACReader older version (i were using ver 9.14) not displaying thumbnail. After having installed the newer version, i can see the thumbnail again.

I guess this can be marked as solved now. Thx again!
