Standardized creative image/preview field names across providers to help with proper selection

Creative image and preview fields now follow a consistent, self-describing naming convention across ad providers, so you can tell at a glance what each field holds and which one to pick. Fields are now labeled by the source of the value: (Hosted) fields hold a NinjaCat-hosted copy of the image that reliably renders in reports, PDFs, and datasets and does not expire; (Source) fields hold the platform's own URL, which can expire or only open on the ad platform; and (Platform) fields link to a page on the platform rather than an image. Where a field was renamed, the previous name is preserved as a "Legacy" duplicate so your existing datasets, templates, and saved queries keep working unchanged.

For most providers, the "(Hosted)" field is the one to use when you want an image that renders reliably.

Your existing work isn't affected. Only the display names changed. Field IDs and dataset column names are the same, so existing reports, templates, datasets and SQL transforms keep working. Datasets created before this change will keep showing the old field names. The new names appear when you create a new dataset.
