Why does Photoshop need to preview a change in image size?

[Jonathan Lipkin]

Not really a question, just venting. If I'm changing the size of an image, it's just going look like the same image, only smaller. Why spend time and resources to show me a thumbnail version of a smaller verion of the file? 

To make matters worse, Photoshop just crashed while "preparing to build preview"

Very annoying

PS, this is v 25.12. I've found the most recent version too buggy and crash-prone to run.

This isn't normally something you wait for. I have instant Image Size previews here, even on big and complex files.

Crashing is nearly always GPU-related. Submit a crash report to Adobe so the engineers have something to go by.

Yes this is rediculous. I deal with very large files for entertainment clients (20GB+ is common) and whenever I am in a situation where I have to resize an image, the "Preparing to Build Preview" just gets in the way and eats up time while I wait for it to process. If it's helpful for some, then give me the option to disable!

Are you sure it is not showing the preview at the same time it is resizing the image?  Is there another significant delay after you hit OK?  I have not tested, but I always assumed they were simultaneous.

Depending on image content and pixel dimensions, the resampling/interpolation algorithm can make a visual difference, so that is why it's there.

A checkbox to disable would be appreciated by some users.

You can use a script that I created to resize without a preview:

I think Stephen might be right. Although you don’t need a preview to know that an image is going to be bigger or smaller, a preview can be very practical and useful if you are trying to anticipate whether the details in your 50% enlargement are going to look their best depending on whether you choose Automatic, Preserve Details, Bicubic, or Nearest Neighbor resampling (that isn’t even all the options). And there will certainly be a visual difference between those options.
