Subject: [support] D7, how to move images from field collection to image field

I have a site where field collection was used to store entity images (multiple in one field). I think it is better to have them in an image field (better colorbox support, and views, and...).

Is there any easy way to modify all nodes to store the field from one field to the other?

H Lluís,

I did something similar with "Rules" I had a field with a misspelled machine name and I couldn't live with it, so I needed to copy the misspelled field to the newly created but correctly spelled field. I created a rule which did this copy for me on the "Open Page" event, and then I opened all the pages, which in my case was fewer than 100. This is not a practical solution if you have a huge number of pages, but it worked splendidly for my case and it was dead simple.

Chris.
