Here is one too:

Yeah, I already noticed that.

I'll have to (re-)check all images programmatically. Hopefully this weekend. It probably won't make much sense to report broken images before I've done that.

Image check done. 902 additional images have been restored from backup and 1020 additional images have been unfortunately substituted by the missing image icon.

Current stats:

Total external images: 77622
Working external images (not substituted): 11230
Substituted by backup: 56446
Missing (substituted by icon): 9946

If you still notice irregularities, feel free to report. Obviously the situation changes dynamically.
