NitroImg v1.0.3 - AI Alt Text & Titles

NitroImg now writes image alt text and clean titles, on demand or automatically on upload, and the page scanner has been reworked to find images other tools miss - including page-builder images and ones already converted to WebP.

AI Alt Text & Titles

• One-click alt text - generate descriptive alt text for any JPEG or PNG on a page from the conversion panel. The image is described and written back to both the media library and the live image tag in your content.
• Clean titles, automatically - when alt text is generated, filename-style titles (my-photo, IMG_4872, screenshot...) are replaced with a readable title. Titles you wrote by hand are left alone.
• Convert + Alt in one pass - a combined action converts images to WebP and writes alt text in a single run, with one summary at the end.

Automatic on Upload

• Auto alt text on upload - a new setting generates alt text and a clean title for every new JPEG/PNG upload, separate from WebP conversion. Skipped automatically when an image already has alt text.
• Independent toggles - auto-convert and auto-alt are now separate switches, so you can run either, both, or neither.

Bulk Actions

• Three bulk actions in the posts list - select multiple posts or pages and run Convert to WebP, Generate Alt Text, or Convert + Alt across all of them at once.

Detection Fixes

• Finds page-builder images - images inserted without a wp-image class are now matched by filename, so they no longer slip past the scanner.
• Resolves converted .webp URLs - an image whose source already points at a converted .webp is mapped back to its original JPEG/PNG attachment, so previously converted images are still detected.
• Smarter "missing alt" - camera-style and bare-filename alt values (IMG_3801, DSC0019, or the filename itself) are now treated as placeholders to replace, not as real alt text.

Fixes

• Upload conversion reliability - auto-convert on upload no longer skips silently when the credit balance can't be read; only a confirmed empty balance pauses it, and uploads are never blocked.
