Everything about Metadata

A scratch is thin and disagrees with its surroundings in almost every direction at once. A real edge disagrees in one or two. That single difference finds the damage with plain arithmetic, and an inpainting model fills what you agree to. All of it in your browser.

A real product photo on a generated background gives itself away on exactly three axes: light direction, shadow quality and perspective. Here is the physics in plain words, a browser tool that walks you through all three checks on your own composite, and the prompt lines that stop the mismatch happening in the first place.

Two things go wrong with web fonts: the licence nobody opened, and the layout that jumps when the font finally arrives. Both answers are already inside the file, in tables you can read in your own browser before you serve a single byte.

Every photograph carries a block of tags nobody looks at: camera, lens, exposure, three timestamps, and often the coordinates of the room it was taken in. Read yours in the browser, then learn what each field means, who wrote it, and what quietly removes it.

The photograph looked right in your editor and flat on the site. Here is where WordPress and its plugins drop the colour profile, and the export habit that ends it.

WordPress has a built in image editor most people never open. Here is what every control does, exactly which files a save writes to disk, where the backup of your original lives, and why the Apply changes to radio buttons vanished.

A media library that takes thirty seconds is not one slow thing. It is a database query, a metadata prime, a JSON build in PHP and eighty image requests, stacked on top of each other. Here is how to measure which one is hurting your site, and the fix order that actually moves the number.

WordPress stores every upload as a post, not as a file in a folder, which is why the media library has no directories to organise. Here is what the uploads folder really is, why moving files by hand breaks images everywhere, and how taxonomy-based folders solve it without touching the disk.

WordPress keeps the file you uploaded exactly as it arrived, sitting next to the resized copies it actually serves. If that file came off a phone, it very likely still carries the coordinates of the room it was taken in.

A character counter says two strings are the same length. A search result says one fits and the other does not. Search engines truncate by pixel width in a specific font, and the numbers are further apart than anyone expects.
