I would like to change themes on my blog but have come up against a problem regarding featured images.
My current theme allows for the uploading of an image to the post and then creates a thumbnail of the image to use on the excerpt.
The theme I wish to change to requires the thumbnail to be a featured image. It will require an additional step to select the image a second time but I can accept that.
The biggest problem I can see is creating a featured image for all the preceding posts that will be brought from the current theme. Is there a way of tagging the currently used images a featured images so they will show as the thumbnail?
We're talking about nearly 2,500 post/images
