### Responsive Images in WordPress 4.4
Images uploaded to the Azure Storage service will not automatically receive responsive versions. Images added through the WordPress Media Loader *should* get automatically converted to responsive images when inserted into a post or page. We are investigating options for full support of responsive images in the plugin.

### Media Library Editor
Media editing tools are currently not working. The edited images are not uploaded to Azure Storage. Will be fixed in future releases.

### Azure Storage Account Migration
At the moment, changing the Azure Storage account (and blob URLs) requires to manually update data in the WordPress database.

Data should be updated in these tables:
1. `wp_options` (or `wp-config.php` or Settings > Microsoft Azure): plugin settings
2. `wp_posts`:
- links in `post_content` of pages and posts (rows with `post_type` = `page` or `post`)
- `guid` of rows with `post_type` = `attachment`
4. `wp_postmeta`: `meta_value` of rows with `meta_key` = `_wp_attachment_metadata` or `windows_azure_storage_info`

**Note:** data in `wp_postmeta` is PHP serialized, it cannot be updated with simple search-and-replace. There are multiple ways to do it:
1. Using WP-CLI, detailed instructions [here](https://dba.stackexchange.com/questions/64675/replace-string-within-serialized-data/239923#239923).
2. Directly inside WordPress, using the [Better Search Replace plugin](https://wordpress.org/plugins/better-search-replace/).
3. Using an external tool that supports PHP serialization, like [Search Replace DB](https://github.com/interconnectit/Search-Replace-DB).
