What does “Custom upload structure” mean?

The custom upload structure can be easily set in the media settings of the Pro version. Here is a little example how the WP standard upload looks like:
wp-content/uploads/2016/11/myimage-150×150.jpg
… and after you set a custom upload structure it can look like:
wp-content/uploads/2016/11/thumbnails/medium/myimage.jpg

Inspection of plugin source files

Most plugin files (PHP, templates, assets) are in the ZIP in human-friendly, unprocessed form (soure files).

The plugin’s JavaScript/TypeScript is bundled (e.g. by Webpack) from plugin-specific packages and third-party open source to produce build files. Each build ends with //# sourceMappingURL=… to source maps with the original, human-readable code; these maps are public and the included source code can be inspected by anyone directly in your browser, if you have installed the plugin.

To conveniently view the complete codebase of the consumed script in e.g. Chromium/Google Chrome, open ⋮ > More tools > Developer tools > ⋮ (in DevTools) > Settings > Preferences > Sources and enable “JavaScript source maps”, “CSS source maps”, and “Allow DevTools to load resources, such as source maps, from remote file paths”. Reload, then open DevTools > Sources > “devowl-local-files” to inspect all readable sources.

Source maps are hosted outside the ZIP to keep size manageable; otherwise the plugin could exceed limits of web hosts and become non-installable.

The repository with all source files can be do be inspected by anyone at assets.devowl.io/wordpress-plugins-source-code.zip. Please check out the README.md in the repository to learn how to get started!

Reviews

Just no

By Nikodemsky on April 12, 2024

Another freemium plugin that's not even do what it's advertise.

Stopped after about 30% of regeneration process, told me to rate the plugin and did not even allowed me to regenerate missing sizes - i need to regenerate all of them.

Most of the features are blocked under paywall.

That's not the proper way of introducing your product.

Thumbnails

Hallo,

Thumbnails fuktioniert sehr gut. Konnte alle Fotos wieder herstellen.

Good plugin, terrible marketing!

By PortMacOnline on July 18, 2022

Before you can use the plugin, you are FORCED to agree to send technical data to the developer, which is against WordPress terms! They do this by forcing you to agree to check a box saying that you have read the Privacy Policy, which I don't mind, AND agree to sending technical data to the developer, because both are included on the same check box, and if you don't check the box, the plugin won't work! The stupid thing is that the plugin itself works okay, so if it weren't for this coercion, and then nagging me to leave a rating for the plugin, I would have been more than happy to check out the Pro version, instead they have lost a potential customer AND got a 1-star review from me.

Easy to use; great UI

The plugin author(s) must have put a lot of effort into the user interface; it's beautiful! They have made a product that works nicely and is a pleasure to use.

Great and up to date

By maxi944124 on February 19, 2021

Ich war schon verzweifelt. Kein anderes Tool hat funktioniert, nach dem Theme Wechsel... die anderen brachen immer wieder ab... habe nun mehere Tage an diesem Mist gehangen... doch mit dem hier habe ich meine ~17.000 Bilder für das neue Theme erzeugt. Funktionierte einfach! DANKE!

Just works!

Lite is useless

By myuption on December 3, 2020
