I have been trying to upload an animated WEBP file to use as part of a post, however I get an error that says the file is “too wide”.

{"data":{"files:null,"msg":"Too wide"},"state":"success"

The file in question has a resolution of 889x500, and a file size of only 3 MiB. Is this a problem with feddit.uk’s image upload settings specifically, or is there a general issue with Lemmy and pict-rs?
