I'm trying to delete excess unneeded duplicate image sizes from my Media Library which is severely slowing my load times. I followed some recommended training here (Boomerang08) which called for:
1) Delete ALL duplicate image sizes in the Media Library, then reload ONLY the one FULL SIZE image you intend to use.
2) In the Dashboard, click on Settings > Media and change all defaults to zero (see below screenshot) and uncheck the "Crop Thumbnail..." - to prevent duplicating the excessive image sizes again on the reload.
3) By changing the above settings, when reloading only one FULL SIZE image, 3 duplicate images in different sizes will not be saved into the Media Library.
Now there should be only 1 image size for each image in the Media Library. In my case, the images are 300 x 225.
As you can see after completing these steps from the following screenshots, the Attachment Display Settings CONFIRMED there is now only (1) 300 x 225 size of each Image in the Media Library.
YET when I check the Image Optimization results in the Media Library stats (Media > Library), I now EXPECT to see something like only this for each image:
"1 Size Compressed (+)
Reduced by x %.." for each of the 3 images.
But INSTEAD when I go to Media > Library to check the far right column under "Image Optimization", I see the surprising result of this last screenshot showing 3 reloaded images in 5 size compressions:
Note the latest EWWW Image Optimizer (4.06) is activated.
Why does the result show it 's compressing 5 sizes, when clearly only 1 size of each image was reloaded?
(I double checked again, the old images with 3 duplicate sizes were ALL deleted from the Media Library)
Can anyone explain to me why this is happening?
