Should Re-saving a Blog Post Generate New Image Sizes

I was under the impression that if I re-saved a blog post, any new image sizes that I've declared would be generated?

At the moment, I'm having to re-select the same asset in the asset chooser, and then click save for the new size to be created.

Yes, they should be. How are you selecting the images?

The images are already selected – I'm redesigning and old site and have updated to Perch 3. Before updating to v3, I imported an up-to-date version of the DB to local, and pulled down the images from production.

The images render fine, and are showing in the control panel, but when I re-save the post, the new image sizes aren't generated. To get the the new image sizes I have to click on the image to open the asset panel, choose the same image, then hit save.

Are these in type="image" fields?

Yes.

From my post.html template:

<img src="<perch:blog id="image" type="image" label="Main Image" width="1400" crop="true" />" alt="<perch:blog id="postTitle" />" />

Re-saving the content is enough to generate any new sizes.

That's what I thought, but it doesn't.
