According to your screenshots, you have almost 3,000 (resizes count too), so where did the other 2,000 go. It generally ends up being an issue with a plugin that is generating images on-the-fly and not caching them to disk. I’ll take a look at the logs, and let you know more.
Ok, the logs definitely show 5000 images optimized, but there is some duplication in there. Did you empty the table or force a re-optimize during the bulk optimization?
I did not! I read that if I did do a force reoptimize that the space would be used. Hmm. So, when the limit says it will reset, do I get another 5,000 next month?
The only other thing I can think of is if you ran some sort of watermarking or another bulk operation with another plugin. Any time an image is edited or modified in wordpress using the wp_image_editor class (which is the normal/proper way to do it) the image will get optimized.
So if you ran a bulk process to regenerate thumbnails, for example, it will optimize those as they are regenerated automatically. According to the logs there are over 1,000 images that were optimized twice,or at least that had identical filenames.
Several that I looked at showed different starting sizes, which seems to indicate that perhaps the modification was only in the metadata, since the ending sizes are identical in most cases. This is seeming eerily familiar to another case I just dealt with, and I don’t know that the person ever tracked down what the root cause was.
If you’d like to try and figure it out, please post a list of all the plugins you are using. Otherwise, you can simply purchase another subscription for 5000 images to finish off your bulk optimize.
The subscriptions renew monthly, but you can purchase additional subscriptions at any time, and they get added to your existing api key. You can cancel the extra ones right away if you’re worried about forgetting to cancel later, and the quota will stay on your account until the end of the billing cycle.
