Email html with images

A image set through URL is possible.

I guess you want an attached image file to be shown as an embedded image within the text? Like:
Slogan <img src="cid:logo_src" /> Text Text ... ?
I haven't checked recently, but I doubt that such a feature is supported by CI_Email class.

Thanks Ivantcholakov and others,

I found the problem... after put site online, it worked fine. One problem was that the files are case sensitive and the picture extension was .PNG, while I was trying to access .png.!
