Blog function from Flickr to WordPress shows html not images.

When I upload an image from Flickr to WordPress by e-mail with the Blog This button in Flickr. In the post on my blog there only appears html code and not the image.

You can see it here: https://www.olafc.nl

When I check this with the html layout in Flickr it appears that all the < and > (don’t know the name for these kind of brackets) are removed. But how this can happen, that is the question to you.

I have had this with an old installation 2.5 and 2.6. And it remains in 2.7. I have tried it with the standaard themes and with custom themes. Did not make any difference.

This is also a good question for the Flickr forums but perhaps anyone here experienced the same and therefore I have posted it here also.

I hope you can help me.

Kind regards.
