I went looking at both of those software packages and couldn't find configuration screens for either. Do either of them have an FTP configuration section? If so, just enter your path to upload images as such.
>/public_html/path-to-image-folder/
Set your blog image path as such.
>/path-to-image-folder/
You shouldn't need to change your image folder to 777 permissions if you are using FTP from either of those packages.
