Thank you @onlyME for this work, this is a great plugin.
Anyway, I missunderstood how content is selected.
I tried to play with "sort by" option but I'm not totally satisfied by plugin behaviour.
For example, with "Sort by last update" setting:
- Yesterday, last post of a topic with an image (I activated "only topic with image" feature) was shown
- This morning, this post disappeared : I guess that's because a new message without image has been posted after but I don't understand this behaviour: if the last message of a topic has no image, so it seems that the thread is not considered anymore by your plugin, strange behaviour
Plus, it doesn't work for some images, the result is that I get the "no image" display even if I checked "only images", maybe a filesize issue?
