@emilysmith Hiya :) The file size limit is currently 10MB with a max image size of 12800 x 5000 pixels as of typing. The platform will attempt to resize anything on the upper end of this scale so the topics load faster. The full size images are still available when clicking the image.
If you're able to get any pics you want to share below 10MB that will work natively here. I haven't increased this limit in a while so if it's needed I'll consider the implications against the existing storage pool.
