About this tag
PNG is a widely used lossless image format on Windows, frequently discussed in the context of file conversion, metadata, and file association issues. Users often seek tools to convert PNG to or from other formats like JPEG, AVIF, or legacy .cpt files, and to manage PNG metadata such as date stamps. The format's larger file size compared to JPEG is a common concern, especially for screenshots, prompting questions about changing default screenshot formats or using optimizers like XL Converter. File association problems, where browsers like Yandex hijack PNG files, are also a recurring topic. Discussions cover both practical troubleshooting and technical exploration of PNG's byte-level data.

    { SOLVED } Can I get pictures on the preview pane?

    I am sure at one time I could see the picture in both the navigation pane and the preview pane of windows explorer. Now all I get with jpgs, pngs etc is an icon with a pair of blue mountains on a blue background with a moon in the sky? Is there any way of getting the pictures back?
