Hi @unreal spoke. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, there could be several reasons why the image view transition is not working in Astro v4. Here are a few possibilities:

1. Directives only work in .astro files: According to a comment (https://github.com/withastro/astro/issues/8983) on GitHub, the transition: directives (and all directives, such as client:) only work inside of .astro files. If you're trying to use these directives in a .jsx file, they won't work. Instead, you can use CSS to create a shared class name for the transition.

.my-image {
  view-transition-name: noenemies2;
}

2. Dynamic view-transition-name: If the view-transition-name needs to be dynamic (such as for multiple images on the page), this is not supported via shared CSS classes. In this case, a dynamic view-transition-name can be added via an inline style property, to ensure unique transition name keys.

<img
  {src}
  {width}
  style={`view-transition-name: ${src.replace(/[^a-z0-9]/gi, '')}`}
/>

3. Issues with <ViewTransitions />: There have been reported issues (https://github.com/withastro/astro/issues/9368) with the <ViewTransitions /> component causing errors. If you're using this component, it could be the source of the problem.

4. Discrepancies between dev and prod: There have been reports (https://discord.com/channels/830184174198718474/1151397066212388924) of view transitions working in development but not in production. This could be due to differences in the environments or configurations.

If none of these solutions work, you may want to check Astro’s issues on GitHub (https://github.com/withastro/astro/issues/) for any reported issues, or to file an issue yourself.
