Hi @drpayyne. Thank you for your contribution
Here is some useful tips how you can test your changes using Magento test environment.
Add the comment under your pull request to deploy test or vanilla Magento instance:

• @magento give me test instance - deploy test instance based on PR changes
• @magento give me 2.3-develop instance - deploy vanilla Magento instance

For more details, please, review the Magento Contributor Guide documentation.

Hello @drpayyne,
I guess there is no need to add the preview images with high resolution. Magento still renders them in 800x800px. Thus it should be the most suitable size for preview images.
Could you please cut the images to be square and reduce the resolution to 800x800px?
Please, also squash all commits into a single commit in order to clean up history, after the changes are done.

Thank you!

Hello @drpayyne. Thanks for contribution. Do You think it's a good idea to have "Test Category" on Theme's preview?

(It concerns Luma as well).

Having seen Your reaction @drpayyne I'm sorry if I put something not quite correctly in my previous comment. I just meant I had tested the instance with Your PR and there was that image preview. And so did You have an intention to leave there that Test Category?

[drpayyne]

@engcom-Bravo oh no no, I was just disappointed that I left it there by mistake. Hence my reaction. Sorry that wasn't clear. Will push the fix soon. Thank you!

[drpayyne]

@engcom-Bravo, fixed it. Thank you!

[dmytro-ch]

Hi @drpayyne, could you please squash the commits again to clean up history?
