PR Summary

• Enhanced Image Type Support in Helper.php

  • This PR extends the compatibility of our software to now accept AVIF type image files and properly classify WEBP and AVIF as legitimate image types. This includes verifications and displaying of these files inline with the rest of our offerings.

• ImageUploadRequest.php Adjustments

  • This file has been modified to accept AVIF images in our image and avatar uploads. Additionally, this update results in cleaner code as debug logging statements, which were redundant, are now removed.

• UploadFileRequest.php Improvements

  • The AVIF files can now be uploaded as general files with this change. This allows users more flexibility with the type of files they'd like to use.

• Image-upload.blade.php Updates

  • In an effort to make our user interface more accommodating to varied file types, the file input now accepts AVIF as a valid image type.

This looks great - just do make sure that you update that comment and I think it'll be good to go.

Thanks for adding this! on the create asset model page, it states: "Accepted filetypes are jpg, webp, png, gif, and svg. Max upload size allowed is 32M."

Probably would help users to know to add avif in that comment so they know it's now supported. Also any other pages that reference this similar comment.
