Values follow the publisher's public guidance. Workload still changes the real need.

### Minimum

| Operating system | A current supported Windows 10 or Windows 11 release, per the vendor |
| ---------------- | -------------------------------------------------------------------- |
| RAM              | Enough for Windows plus this app. Heavy projects want more.          |

These executables belong to this product when it is installed.

| ImageGlass.exe | Main Windows executable |
| -------------- | ----------------------- |

ImageGlass does not need to start with Windows.

## File locations

| Typical install | C:\Program Files\ImageGlass\\ |
| --------------- | ----------------------------- |

## File formats

JPEG, PNG, GIF, WEBP

## Common problems

### Photos stole the default again

Settings > Apps > Default apps. This is a Windows habit, not malware.

### HEIC missing

Install a codec pack Windows or ImageGlass documents. IrfanView uses plugins instead.

## Getting unstuck

### Confirm ImageGlass.exe

Program Files\ImageGlass is the app. Photos is a Store package.

### Install from imageglass.org

GitHub releases are also official. Random ImageGlass.exe hosts are not.

### Reset ImageGlass settings

The docs name the config folder. This is not Photos reset.

## Alternatives

IrfanView, XnView MP, and Photos overlap. Photos does not replace ImageGlass as a default viewer by quality. It just ships with Windows.

Start with the vendor. Random exe sites are not a support channel.
