WordPress.org

I'm getting a lot of broken links.

The plugin stores the cache folder in wordpress uploads folder. If you get broken images the plugin is unable to create the cache files. Make sure that the uploads folder is read/writable.

It only displayes about 50 images when I set my limit to 100+

Sadly, there are some limitations in both Twitter and Instagram.

Instagram only return about 20 images on a search. You can find more information about it here There is a way to get more results form instagram, but my time is limited so it have to wait for now.

Twitter only return results from the lates 6-8 days, and most of the time this result in 50 - 70 items depending on how popular the hashtag you use it. You can read more about this in the twitter search api documentations here
