The editor we tried already was JCE Editor, and I made a mistake, it crashes when we try to upload images from the user end. So we never even get to the resizing part

Basically our goal is to ease front-end use.
As for the language issues, we have MyContent installed, but it doesn't have ability to post/translate into French. As it stands, to do a french translation of an article, we would have to give the user front end access to upload the english content, then backend access to do the translation, which is impossible, both because it is not friendly towards non-tech people (this is why we can't just give them backend access for both, as well), and it makes the process of translating tedious.
