Problem

oEmbed responses of type: photo have no html field. The spec puts the image in url, with width and height. The generic Code detector only reads html, so for these providers $info->code is null even though the image is right there.

Live reproduction (GIPHY)

$info = (new Embed\Embed())->get('https://giphy.com/gifs/cat-funny-JIX9t2j0ZTN9S');
var_dump($info->getOEmbed()->str('type')); // "photo"
var_dump($info->code);

• master (4.5.1): code is null.
• This branch: <img src="https://media0.giphy.com/media/JIX9t2j0ZTN9S/giphy.gif" alt="Cat Working GIF - Find &amp; Share on GIPHY" width="480" height="480" />, width 480, height 480.

The same happens live with DeviantArt (https://www.deviantart.com/sakimichan/art/Misty-510056679).

What changes

src/Detectors/Code.php: when the oEmbed response has no html, and only then, a new detectFromOEmbedPhoto() checks for type: photo with a url. It builds the tag with Embed\html('img', ...) (src, alt from title, width, height when present, all escaped) and returns an EmbedCode with the width and height.

• An oEmbed html still wins, so providers that send both are unchanged.
• Other types without html (for example link) still fall through to OpenGraph, Twitter and content type, as before.
• PHP 7.4 compatible, no new dependencies, no public API change.

Fixtures

Three page fixtures change from 'code' => null to an <img> code, because their cached oEmbed responses are type: photo:

• tests/fixtures/www.deviantart.com.art-misty-510056679.php
• tests/fixtures/pachunka.deviantart.com.art-cope-145564099.php
• tests/fixtures/www.23hq.com.zzleeper-photo-16600737.php

They were regenerated from the existing cache only (no network). No other fixture changes.

Tests

New tests/OEmbedPhotoCodeTest.php, offline (fake HTTP client, no network):

• photo with title and size builds an escaped <img> with width and height
• photo without size omits the dimensions
• html still wins over the photo url
• a non photo response without html still has no code

Results:

• PHP 8.5.12: OK (241 tests, 591 assertions)
• PHP 7.4.33: OK (241 tests, 591 assertions)
• PHPStan: no errors

Backward compatibility

No BC break. The only visible difference is that code is now filled for oEmbed photo responses where it used to be null.

Replaces #581 (moved from my fork to this repository).
