A fairly unusual php2Bluesky issue was raised recently, via Github, where when a site was being used as a link card and the main image on that site was a GIF it was being converted and sent to Bluesky as a video, which it didn’t like.

Invalid app.bsky.feed.post record:
Expected "image/*" (got "video/mp4")
at $.record.embed.external.thumb.mimeType

I suppose that this makes sense – there can’t be many sites with a GIF as the associated image and Bluesky wouldn’t be expecting that.

A user of my PHP2Bluesky package, Muzikals, raised an issue to say that Bluesky had increased the limits for both videos and images. Now you can upload larger-sized videos of up to 300MB and ten minutes in length, and the limit for images has been raised from four to ten.

I’d planned for this

When developing php2Bluesky I had always thought that there was a possibility that the limits would change and so, rather than hard coding them, I added the limits as constants into BlueskyConsts.php:

    // don't change these unless Bluesky changes the limits
    const MAX_IMAGE_UPLOAD_SIZE = 1000000;
