Hey guys, thanks for reaching out, I’ll gladly help!
@desandes — the plugin is only creating a couple of thumbnails, one for the theme you are using and the second copy for the plugin. All in all it shouldn’t be taking up too much of your space, but do let me know if this isn’t the case, since we’ll be more than glad to take another look.
@shandastiles — or you can just change the URL of the images you want to change and keep the whole custom field unchanged forever. That’s because once you set up your settings in the plugin settings (when you choose which value our the Custom Field our plugin should use for the thumbnails), you won’t have to change it again in the future. This way you save yourself a lot of time.
Once you have set this up, you just add a Custom Field with every new post, set the image you want to use for the thumbnail, while the name stays the same. Also worth noting is that you should keep the images you want to use for thumbnails as square as possible and that they’re not too big. The perfect size would be 151×151 pixels (or bigger), but that is not that crucial. Just don’t use the biggest images you can find, because this can return you some problems.
Let me know if you guys have any more questions or if there’s anything else that’s not completely clear, since I’ll be more than glad to help you out!
Take care & have a nice weekend ahead!
Best,
Silvo
