Converting base64 images to files "for this page" programmatically

Hello,

I'm importing content into Optimizely CMS from an external system. Saving the pages with the external content works fine, but the images are in a base64 "<img src="data:image/jpeg;base64,/9j/4AAQSkZJRgAB ..." format.

When I open a rich text field in Optimizely with such an image, in TinyMCE, the image is automatically saved to "For this page", and the image src is now an url to a regular file on the server.

How can I automate this process, so all image are converter from base64 string to file during the import process, without having to go into TinyMCE in the generated page?

Hello Praful,

I've developed a solution in code. The code you refer to is certainly part of that solution. The solution was a bit elaborate, because you have to find the images in the Xhtml string with the HTML Agility Pack, and then replace the source attribute with the url of the image you have previously saved "for this page" etc.

Oh, I didn't notice you have image as part of raw markup.
