Eagle currently doesn't have a direct feature to hide image materials, but you can use the "Folder Encryption" feature to prevent images in specific folders from appearing in the "All" view. Here's how to do it:

Setting Up Folder Encryption

Select the folder containing the images you want to hide
Right-click on the folder in the left sidebar and select "Password" > "Create"
Alternatively, find "Password" in the basic information section of the inspector panel on the right side and click "Create"
Enter a password and a hint when prompted

Important Notes

After setting the password, the folder will be immediately locked and its files will be hidden from the "All" view
If you unlock the folder during your Eagle session, previously hidden files will reappear in the "All" category
To hide them again, right-click on the password-protected folder in the left sidebar, select "Password", then click "Lock Now"
