Hi there! I see you're having trouble sharing your Pic Stitch collage via email. I'd love to help get this sorted out for you.

Could you tell me a bit more about what happens when you try to share? For example, do you get an error message, does the email app not open, or does the sharing simply not complete? Also, are you using the Pic Stitch app on your Windows machine's browser or in some other way?

Meanwhile, here are some general steps we can try to troubleshoot the sharing issue:

1. Check Internet Connection: Ensure your device is connected properly to the internet, as sharing requires an active connection.

2. Update Pic Stitch: If you're using the app version on Windows or a mobile device, make sure it’s updated to the latest version.

3. Try Exporting First: Sometimes, instead of direct sharing, you can export/save the collage image first to your device. Then, you can manually attach it to an email.

4. Confirm Email App Settings: Verify if your default email app or webmail service on Windows is properly set up to send emails. You might want to try sending a regular email with an attachment to confirm this.

5. Browser Permissions: Since you mentioned WebKit and Windows, if you're using the app via a browser, ensure that the browser has permission to open your email client or send emails.

If none of these work, let me know any error details or what step specifically fails, so I can guide you further!
