disable 2 times crop for super-faster upload

[alexvorn2]

when you upload an image to the media, the images is uploaded, then converted to 3 different images...

1. 150x150 px
2. 300x274 px
3. 1024x936 px (in my theme example)

It can be faster upload if we will remove the action to resize/crop to all these images.

We can resize only to 150x150 px for thumbnail, and after the user uses from the selection menu what images he would like to insert into the post, create the images to this needs... like 300x274 (middle size)...

it is not a duplicate I think... but is related :)
I use that code and can say that is really buggy...

Here's one scenario where having intermediate image sizes generated "on the fly" would be bad:

Say you have a moderately busy homepage (tens of hits per second), where you display a 'medium' image for each recent post. You upload a large image for a post and publish the post.

The first user hits the home page; the 'medium' image for the new post isn't there, so WP sets out to generate it.

Assuming it takes 2-3 seconds to do that, there will already be tens of other WP instances trying to generate the same image.

Server runs out of memory and starts refusing connections or just dies.

Good catch! I will try to find a solution...

maybe to try to resize/crop all images on the fly before publishing the post?
Huh! I am a genius ))))

The discussion should be concentrated in #15311.

Not really. You would have a faster upload, but a slower publishing.
