Thanks for the work on this plugin.
I am using the plugin to either let users post text or one image. I am hiding the title as it is not important but it seems like as soon as the title is generated there is no check if the post submission actually has content. It seems like there is only a check on the title anyway, so also the check image size doesn't seem to work for me.
I am still working my way through the plugin code. Maybe you have some suggestions.
