Overview
If you were ever annoyed about the way WordPress handles images resizing, this is a plugin for you.
What this plugin does is it optimizes the image handling in such a way that images are resized only when they are actually needed. What that means is that if your plugins/theme define a lot of image sizes, none of them will be generated on the image upload (like they would be usually), but only if they are actually requested in that size.
Resizing is done only once, images are later normally served by WordPress, so there is no performance hit.
Plugin also includes a method for removing all of the previously generated image sizes (useful when you install this plugin on a site with a lot of existing media).
TO REMOVE image sizes generated prior to activating the plugin, visit the ‘Tools…

Excellent!

This plugin is awesome even in 2021! I wish I knew about it sooner and that the developer would continue to update it. Works fine though for 3 sites I installed it on.

Doesn’t work as should
by Jek-fdrv·7 years ago
Why it generate all sizes if I have requested only 100 on 100 pixel.
For example I have 20 different sizes.
For post example with id 21 I use featured image.
On the front page I have custom template which use featured img for post 22 with size 100 on 100. Why it generate all other 19 sizes? I dont use for this img all other, just 100 on 100.
