WordPress.com Staff are continually working to improve our user experience. The result of their latest work is a welcome media update change to the way WordPress resizes images when theme changes are made.
Previously, if we changed themes to a dramatically different theme we had to resize images and that sometimes involved hours of work, not to mention, a messy looking blog during the process.
The good news is the September 20th update is especially designed to allow images to automatically resize after we switch themes.
Every theme has a maximum displayed image width. The sizes listed at Settings > Media determine the maximum dimensions in pixels to use when inserting an image into the body of a post or a page.
The update insures that the sizes set in Media > Settings are applied to images using classes such as “size-medium” (common).
What happened to my pictures?
If this update changed your images in a way you didn’t expect, please see this forum thread where Staff are at the ready to help with the transition and where these short term fixes are provided:
If your images are using classes like “size-medium” (common) and you want to change them all at once, go to Settings > Media and make sure the max widths and heights are set correctly there.
Image resizing bug tracking
I’m tracking three bugs related to image resizing that I hope we will be able to get reviewed this week. They are:
2. Captions aren’t resized to match images that were resized.
3. Width and height aren’t correct for resized images in portrait mode – fixed!
