Until yesterday, I believe that some of my large .jpg pictures on the Bob's Burgers wiki were appearing as thumbnails without a problem. Now someone has alerted me and I find I'm getting the "Error creating thumbnail: Invalid thumbnail parameters" thing on them. These images are larger than 12.5 megapixels but I believe they worked fine up until yesterday. Has something changed that means I can no longer see the thumbnails of these large images or will this mean I should downsize them?
