# Objective Fixes #15940 ## Solution Remove the `pub use` and fix the compile errors. Make `bevy_image` available as `bevy::image`. ## Testing Feature Frenzy would be good here! Maybe I'll learn how to use it if I have some time this weekend, or maybe a reviewer can use it. ## Migration Guide Use `bevy_image` instead of `bevy_render::texture` items. --------- Co-authored-by: chompaa <antony.m.3012@gmail.com> Co-authored-by: Carter Anderson <mcanders1@gmail.com>
