With the introduction of 2K textures, SL should provide two upload options to accommodate users who might forget to downsize their images:
Option 1: For images up to 1024, this option will automatically downsize the images for the user, just the way it used to be.
Option 2: For images with resolutions higher than 1024.
Note: Both options should be available for single and bulk uploads.
These options will help prevent accidental bulk uploads of incorrectly sized images. Sometimes when I bulk upload, I might miss one that I forgot to downsize. No one likes a costly surprise when a mistake happens.
