Mosaic PRO — Photo, Video & Audio Gallery with Responsive Layouts 1.0.40

New: image rotation and flip tool

Moderators can now fix incorrectly oriented photos directly from the gallery instead of deleting them. Rotate left, rotate right, rotate 180°, and flip horizontally or vertically — available on the media page and in "My media". All sizes (thumbnail, medium, full) are regenerated automatically.

Two new permissions control access:

• Rotate and flip any media — for moderators
• Rotate and flip own media — lets users fix their own uploads

Neither is enabled by default, so grant them to the relevant user groups after upgrading.

Fixes

Fixed image processing failing on servers where the PHP fileinfo extension or ImageMagick is not available. Image types are now detected from file contents rather than relying on those extensions.

This affected both regular uploads and, in particular, the XenForo Media Gallery importer: on affected servers every item failed with a "GD cannot load source image" error and nothing was imported. If your import failed for this reason, you can simply run it again after updating — existing items are skipped, so nothing gets duplicated.

Note: this update adds a database column, so make sure the upgrade completes fully.

Fixes and improvements

• Fixed a fatal error during license validation caused by unqualified PHP constant references, which failed on certain server configurations.
• Lifetime licenses now correctly remove the "Powered by Mosaic PRO" footer across all gallery pages.

No database changes in this update.

Note: license validation requires the PHP sodium extension. If your host has it disabled, the add-on will now tell you so directly — ask your hosting provider to enable it.

1.0.38 — Fixes a fatal error when deleting a category from the Admin CP. No database changes.

Trial license recovery

If a trial had already been issued for your domain, requesting a new one returned "trial already used" with no way to retrieve the existing key. The trial request now recovers your existing license automatically and activates it, so you're no longer stuck if you lost the serial after a reinstall.

If the recovered license can't be activated (for example because your Board URL no longer matches the licensed domain), the serial is now shown to you along with the reason, so you can resolve it yourself.

No database changes in this update.

1.0.36 — Fixes an installation error ("Expected valid expression") that occurred on some XenForo/PHP configurations during install. No database changes.

New feature: you can now protect your photos with a personalized text watermark!

What's new:

• Custom text watermark — when enabled, users can add their own watermark text while uploading (e.g. their name or © credit).
• The watermark is permanently applied to the bottom-right of the full-size photo, with an elegant script font — thumbnails stay clean.
• New admin option to enable or disable the feature for your gallery.

The watermark is optional: leave the field empty and the photo is uploaded with no watermark, exactly as before.

As always, feedback and suggestions are welcome. Enjoy!

Thank you for the feedback and bug reports! This update resolves a few issues reported after the first release.

Fixed:

• Fixed a template error ("Filter round is unknown") that appeared when opening a media item with GPS location data. Maps and coordinates now display correctly.
• Fixed the gallery behaviour when the lightbox is disabled: clicking a photo now opens its media page correctly, instead of showing an empty overlay.

Recommended for all users — especially if your gallery contains geotagged photos or if you run with the lightbox option turned off.As always, your feedback and bug reports are very welcome.

Thank you for helping make Mosaic PRO better!

This update fixes a template compatibility issue affecting installation on some XenForo 2.3 setups.

Fixed:

• Fixed an "Expected valid expression" error that could prevent installation on certain XenForo 2.3 configurations.

As always, feedback, questions and bug reports are very welcome!
