I recently installed Corel Photo-Paint 8 on my OS and the program associated itself with all of the pictures on my computer. I wanted to changet his and I took some bad advice and went into folder options then into file types. I deleted the extension JPG and then restored it or whatever. Anyways now I can no longer view my pictures as thumbnails when I open a folder. It only has squares with the icon of the program associated with the file. Can anyone help??
