Hello @shamai
Hope you’re doing well!
I’ve tested the “Resize my full size images” option on my end and it is working well, original images were resized to set width and height.
Would you please let us know more information about the issue on your site? What are the enabled settings at the moment? What are the exact dimensions added to the Resize my full size images option?
I mean dimensions were set to be below 2000px for full sized images and I see 6k image sizes in the media library
Please smush one image manually on your site via the media library, check the image dimensions before optimizing an image with Smush, and after optimizing an image, will dimension be changed?
If the dimensions will not be changed, please make sure there is no conflict with another plugin. Deactivate all plugins besides the Smush and optimize an image again, see if this has resized it.
If all is well, start activating one plugin at a time, every time checking how the image resizing is working.
Please share a link to your site so we could have a look.
Please advise,
Cheers,
Nastia
