Bluesky rejects image blobs over 1,000,000 bytes, so the shared image always used the WordPress "large" size and often looked blurry. Pick the largest available size (full, 2048, 1536, large) whose file is within the limit, and fall back to the original URL on any failure so behaviour is never worse.

Summary
Images shared to Bluesky were low-resolution/blurry because the pipeline always used the WordPress
largesize (~1024px). That size was used because Bluesky'suploadBlobendpoint rejects images larger than 1,000,000 bytes.This picks the largest available image size that still fits the limit — trying
full→2048x2048→1536x1536→large— so the sharpest acceptable image is uploaded. For external images, an unresolved attachment, or when nothing larger fits, the original URL is returned unchanged, so it is never worse than before. The limit and size priority are filterable (rop_bluesky_max_image_bytes,rop_bluesky_image_size_priority).Will affect the visual aspect of the product
