Feature/preload image pdp

[gabridevs]

What problem is this solving?

This change improves the loading performance of product images by preloading the main product image via a tag in the ProductImage component. It ensures that the primary image is fetched earlier in the page load process, reducing time-to-visual-complete and enhancing user experience, particularly on slower connections.

How to test it?

You can test this by checking the network activity in the browser’s developer tools. The main product image should be listed as a preloaded resource, and the page should render the image faster compared to the previous behavior.

This PR seems to be based on the same branch as of #1120.
If this was not done for a specific reason, I would ask to make them independent of each other in case we need to rollback any specific deploy

[vmourac-vtex]

I would also request that you:

• fix conflicts in CHANGELOG.md
• provide an up to date and working workspace

Yes, this was done intentionally. The changes in this PR build directly on top of the work from #1120, and separating them would require duplicating logic or restructuring shared components. Keeping them together ensures consistency and avoids redundant code, so I’d prefer to keep them coupled unless there’s a strong need to isolate them.

I've separated this feature into a new PR based directly on master, to avoid coupling with #1120. Please review [new PR link] instead. I’ll close this one once it's approved.

Thanks for pointing that out! You’re right — the previous PR was based on top of #1120. To keep things clean and independent for deploy and potential rollback purposes, I’ve now created a new PR directly from master with just the preload-related changes: #1137

I'll close this one once the new PR is approved and merged. Let me know if anything else is needed!

@gabridevs
The use of AI, when properly applied, increases our productivity and helps us understand the code, allowing us to deliver solutions more quickly.
What happened here is the opposite of that. Posting an AI-generated response without even reviewing or questioning what was produced results in more work for both parties.
The Store Framework team sets aside time—among internal priorities—to review external PRs, and that time has just been wasted. Your post provides two contradictory answers to the same review request, and neither of them correctly addresses what was asked.

I kindly ask that you carefully review your work, regardless of whether it was assisted by AI or implemented manually. I also ask that you go over all the requested review changes from past interactions, and only then request the PR review again.

If you have any questions, feel free to ask.

Hi @vmourac-vtex,
You should be more precise about what the problem is in this answer, if the duplication of the comments I try to reopen it differently otherwise I don't understand what the problem is.

Hi @vmourac-vtex,
I opened the new PR at this link: #1137

[vmourac-vtex]

Hi @vmourac-vtex, I opened the new PR at this link: #1137

Hi @gabridevs.
I noticed the PR when you first mentioned it above. It also contains issues since the changes proposed in #1120 (branch gabridevs:master) and #1123 (branch gabridevs:feature/preload-image-pdp) are mixed together in it.

I propose a different solution. Since the three original PRs need similar fixes (#1120, #1122, #1123) I will list a proposal for fixes on all of them here.

Instead of trying to fix the current branches, lets start from scratch. We need an up-to-date master branch. After that we will create feature branches for each PR only with the code relevant to that PR:

You can create a fork from scratch, but GitHub won't allow you to have multiple forks of the same repo. So, if you don't want to delete your current fork and recreate it, I suggest you

• Store your master changes in a backup branch: git checkout -b master-backup
• Delete your current master branch: git checkout -D master
• Create a new master at the latest common commit before your fork diverted from vtex-apps master (upstream): git checkout master 1a09940cb7afa393e00507bd23c48b389fb58f7d
• Set your branch as master in the upstream: git branch --set-upstream-to=origin/master master
• Force push your changes: git push --force
• Pull the latest changes from the upstream: git fetch upstream
• Rebase your master with the latest changes from the upstream: git rebase upstream/master
• Push the changes: git push

Now you have a clean and up to date master, in sync with vtex-apps. Let's create feature branches for each PR:

• Make sure you are on the master branch: git checkout master
• New feature branch for Custom thumb dimensions: git checkout -b feature/custom-thumb-dimensions
• New feature branch for PDP Image Preload: git checkout -b feature/preload-image-pdp-new
• New feature branch for PDP Fetch Priority: git checkout -b feature/pdp-fetch-priority-new

Now you can copy/paste the required code from each original branch to the new feature branches. Since the original branches for preload-image and pdp-fetch-priority had code that was mixed with the custom thumbs solution, remember to only copy/paste the code that is related to the change you are proposing in that PR

Open PRs for each of the new branches and we iterate from that, with a clean slate

[vmourac-vtex]

Theoretically the change makes sense, but we could not validate it in the provided workspace
Ensure that in your provided workspace we can verify that:

• We can see the preloaded image in the head component
• We can ensure that the preloaded asset is clearly prioritized in the developer tools

hi @vmourac-vtex, I close this PR as we have developed a custom component in our store.
Thank you for the support!
