When updating galleries, any existing v1 images in the gallery are now upgraded to v2 to avoid an inconsistent mix of resamples. Let me know if you notice any issues with this.
A conversion process was also started to gradually migrate existing public galleries to v2, working its way backwards. This process is currently estimated to finish around mid December. Of 2026.

In short, EH is migrating its resampled images from jpg to webp, which gets better image quality at the same size, and 780x resampled is changed to 800x. It's applied to new galleries already and rolling out to old galleries.
Besides it's possible that some galleries are uploaded as webp format.
For now there's no plan to convert them on script side, considering it's resource consumption and makes resampled images looks worse. It's like converting AAC to MP3, from lossy to lossy, which worsens the quality.
I have no idea what's going on with this now, but it randomly started switching all the file extensions to webp even when they were originally jpg or png. This tends to make it impossible to use them in readers.
