Sorry to bother you again. I tried to embed a logo in my newsletter. I managed to get it coded and tried to insert < img src="image/jpeg;base64..." / > Although in the preview in the html editor this works, again when switching editor or trying to save, it errors. In a normal WordPress page it works ok. I see there is a plugin from Tribulant, but I guess this should work also. I don't want the recipients having to download the logo.
