I am currently using CKEditor for my hmtl editor in my CMS. I want to use something that has a really good image upload and resize feature, like Wordpress does. Anybody have any ideas on what the best CMS system is to use?
The best answer you will likely get here or anywhere else will always be personal preference. If you like the WP features then dig into the open source software and figure out which RTE it is you are looking at and download it and implement it with your application.
