Collect A Copy Of All Your Png’s For In A Folder

For Ex. Name The Folder image and put it in the desktop

Then Go To Terminal And Change Directory To The Folder you Have Moved The Photos In

cd desktop/image

Open It And Search In It For

If you find The Number Next To it Is Different Than 8 Then You Got The Mistaken Image

Open This Image (Or Images) In The Preview App Then Export It To The Same Format And Make Sure To Select 8 Bit Color Depth (Note If You Select Multiple Images You Don't see The Color Depth Selection But It Is Still Working)

Copy And Replace The New Images With The Old Once.

Also Do The Following As An Addition To What I Have Posted Earlier
