ChangeLog
3.3.2
- Added: Support for conversion at original size — when
thumb is 'full' or [0, 0], images are converted (WebP and original format) without resizing.
- Added: In
liteimage_downsize(), size [0, 0] now returns the original image dimensions.
- Added: In
get_thumb_size(), support for 'full' and [0, 0] with correct size_name in format liteimage-{width}x{height}.
- Fixed: Safe reading of
width/height from attachment metadata in liteimage_downsize() when keys are missing.
3.3.1
- Fixed: Thumbnail filename conflicts when multiple images share the same filename. Added attachment ID to thumbnail filenames to ensure uniqueness.
- Fixed: Format changed from
{filename}-{size_name}.{ext} to {filename}-{attachment_id}-{size_name}.{ext} for all thumbnail variants (WebP, original format, and retina @2x versions).
3.3.0
