hi i test that it happen just when i use refresh in shiori and if i use ctrl + F5 it fix.
somehow refresh can't clean cache of browser but i don't find why it happen for some of bookmark yet
@fmartingr do you have any idea?

update: i test that in firefox.

update:
change this part

thumbnailStyleURL() {
    const cacheBuster = new Date().getTime(); // Unique timestamp
    const thumbnailWithCacheBuster = `${this.imageURL}?cache=${cacheBuster}`;
    return {
        backgroundImage: `url("${thumbnailWithCacheBuster}")`,
    };
},

what do you think? any better solution?
if it is fine to you send i will send a PR to fix that.

@DesarrolloAntonio can you test this on your system and report if problem will solve with this change for you too?

In the Android app PageKeeper, I fixed it with a similar solution, but instead of a timestamp, I added the "modified" field.

// Append 'lastUpdated' query to image URL for cache busting. Forces retrieval of updated images.
val imageUrl = "${serverURL.removeTrailingSlash()}${bookmark.imageURL}?lastUpdated=${bookmark.modified}"
