Upfront is not working with Imsanity plugin

Imsanity plugin, the most popular one to resize and compact images has these three options:
Images uploaded within a Page/Post
Images uploaded directly to the Media Library
Images uploaded elsewhere (Theme headers, backgrounds, logos, etc)

However, none of them is working with Upfront uploader, why? Do you have any other plugin to suggest me then? I think it was working for the previous versions. Thank you!
