If your theme is written properly then you can use https://wordpress.org/plugins/simple-image-sizes/ plugin to change the size of any thumbnail.
If you do use it, then all new thumbnails will be of the new size and all old thumbnails will keep the old size, unless you perform the thumbnail regeneration from within that same plugin, in which case all thumbnails will have the new size.
Hope this helps, and makes sense. 🙂
Hi @sinip,
I was wondering if I could change the default 1024xsmth WP thumb and regenerate only that size. But I am afraid that in my posts, that are already using the 1024 image size, they ‘ll end up with a “broken” icon.
The truth is that I am deleting manually the thumbnails one by one to gain some extra space. So if I regenerate the thumbs again, I ”ll get back all those unnecessary sizes which I erased with much effort. You see, I made the mistake to upload my images with great filesize. Well, that’s not so bad because I wanted to be sure about the quality. But you see in my posts I use the large size which is resized finally, to a 910×607 thumb. I would like all my 1024 thumbnails to be converted to a 910x 607 thumb, so I can decrease a bit the total filesize and gain some space in my server.
I know…it is too complicated even for me who I am writing this post. I am giving up already. 🙂 Thank you for your time!
Well, what you can do is download the whole /wp-content/uploads/ folder to your hard drive (all images should be there) and then fire up the plugin and regenerate just that thumbnail size. There’s setting that allows for individual thumbnail size regeneration.
If anything goes wrong, you’ll have all images intact and you can put the back
