I get that error after adding:
config.extraPlugins = 'doksoft_image_embed';
to the config.js for ckeditor. The editor all not work at all unless I remove the extraPlugins line.
I extracted the files to the plugins directory as the instructions dictated.
I am using ckeditor 3.6.6 and Chrome 39.0.2171.

Dear Experts,
We are planning to use CKEditor's Easy Image Embed/Upload add ons for one of the application which will be used to draft email bodies. These messages will then be then sent as an email to the readers.
Most of the readers are using outlook 2010 client to read the emails. Any feedback on the outlook compatibility will be helpful.
Also, Is there any evaluation version which I can quickly test before going to buy the licensed copy. please advise.

CKEditor Image Embed plugin supports IE 10+ but do you have any support for IE 9?

I have purchased the CKEditor Image Embed product (single user license).
I am using the html generated by CKEditor including an embedded image as an email body.
The email is delivered fine, but the image is replaced by a block.
If I view the email source I can see the embedded image…
code]<p><img src="data:image/jpeg;base64,/9j/4AAQSkZJRgABA…..ptbeQUUUVzmx//2Q==" /></p>[/code]
Am I doing something wrong, or do you have a suggestion to fix this?
