Hi there! I see you're having trouble sending pictures with the ACDSee app. To help you better, could you tell me a bit more about the problem? For example:

- Are you trying to send pictures via email through ACDSee or through some other method?
- Do you get any error messages or does it fail silently?
- Which version of ACDSee are you using?
- Have you set up an email client on your Windows 10 machine, or are you using SMTP settings inside ACDSee?
- Are the pictures failing to send from your desktop app, or from a mobile sync app?

With a bit more info, I can guide you through the easiest and most effective steps to fix this. Meanwhile, I can share some common points that often help:

1. Check Default Email Client: ACDSee relies on having a default email client set up on your Windows 10 system for the "Send Email" feature to work seamlessly. Please ensure an email client like Outlook is installed and set as default.

2. SMTP Server Settings: If you're sending pictures directly via SMTP in ACDSee, verify those settings are correct—server address, port, and your login credentials.

3. File Format: Sometimes, pictures in certain formats (like HEIC from iPhones) can cause issues during sending. Converting them to JPG might help.

4. Firewall/Antivirus: Sometimes security software blocks ACDSee from connecting to the internet or your mail server. Temporarily disabling your firewall or adding exceptions for ACDSee and related services (Bonjour, for example) can resolve this.

5. Temporary Files: ACDSee might generate temp files for sending. Make sure your system has space and permissions to write to temp folders.

If you've tried any of these already, just let me know which ones and how it went. We'll take it from there with more tailored advice or deeper troubleshooting!

unable to send pics from mobile phone

Thanks for clarifying that you're trying to send pictures from the ACDSee app on your mobile phone. Let's see if we can get this sorted out.

A few questions first to understand better:
- Are you using the ACDSee Mobile Sync app to transfer photos to your Windows 10 PC?
- Is the problem that photos don't appear on your PC, or that sharing directly from the phone app fails?
- Do you see any error messages when trying to send or sync pictures?
- What mobile device and OS version are you using (Android, iPhone)?

Meanwhile, here are some common troubleshooting steps that often help with mobile sync and photo sharing issues on ACDSee:

1. Clear Mobile Sync App Cache/Storage on Phone: Sometimes the sync app on your phone gets stuck. Go to your phone’s Settings > Apps > ACDSee Mobile Sync > Storage > Clear Cache and Clear Data. Then restart the app and try again.

2. Check Network Connection: Mobile Sync requires both devices to be on the same Wi-Fi network. Make sure your phone and Windows 10 PC are connected to the same network, and that your router is functioning normally (sometimes rebooting the router helps).

3. Firewall and Bonjour Service on PC: Ensure your Windows firewall or antivirus is not blocking ACDSee or its Bonjour service, which is used for device discovery in Mobile Sync. You might need to whitelist these or temporarily disable the firewall to test.

4. Reinstall Mobile Sync App: Uninstall and then reinstall the Mobile Sync app on your phone. Users have found this can fix connection and sending issues after device or OS changes.

5. Check File Formats: If the photos are HEIC format (common on iPhones), sometimes sync or transfer glitches occur. Convert the images to JPG if possible or check if there is an update to ACDSee that improves HEIC support.

If these steps don’t resolve it, I can guide you to check more advanced settings or help you gather diagnostic info. Also, if you want, I can provide direct links to relevant community forum posts where users have fixed similar issues.
