I have a page of images that link to specific posts (which is why I didn’t make a gallery), and today I logged on to find that even though they’re all thumbnails, some images are much larger. How can I fix this? Or is there a way to create a gallery where an image links to a specific post?
As far as using a Gallery rather than individual images, there is no way to directly link a Gallery thumbnail to a post, but you can add a link in a caption or image description, which would mean an intermediary step. However, using a Gallery should insulate you from the problem described above.
