On my nodebb instance the settings permit large picture size uploads, but everytime I try to paste a picture in a post I get an error. Same happens when I try and load a moderately large .png file. The error just says error. No details just (error) written after e.g. .....9-image.png](error)

I looked in the logs but no details there either on why it failed. The image posts in this site no problem

It does seem related to the size, as smaller images will load, but both are smaller in memory size than the maximum allowed in ACP
