some examples:
>>>/cure/
with /cure/ the images not showing appears to be more of an issue with the OP preview images being bugged, but the images are still there if opened as single files
/cure/ was active in the 2016-2017 years
>>>/out/
/out/ is a better example, all the images are broken, is that something which happens over time eventually to all boards?
/out/ was active in the 2017-2018 years
>>>/predict/
an other case of broken images
>>>/poll/
