[Feature Request] Option for a custom image association icon about jpegview

[TetraTheta]

As a workaround, you can create your own file association registry entry for custom icon etc.

reg add "HKCR\JPEGView.PNG" /ve /t REG_SZ /d "PNG File" /f
reg add "HKCR\JPEGView.PNG\DefaultIcon" /ve /t REG_SZ /d "C:\Customizations\custom_icon.dll,19" /f
reg add "HKCR\JPEGView.PNG\shell\open\command" /ve /t REG_SZ /d "\"C:\Program Files\JPEGView\JPEGView.exe\" \"%%1\"" /f

For example, this will create JPEGView.PNG association that have C:\Customizations\custom_icon.dll's 19th icon as its icon, and run JPEGView when launched.

You must use SetUserFTA for setting file association, because Windows automatically sets it back into Picture app if the registry is manually modified.

If you want to use ico file, you can just directly provide ico file's location like C:\Customizations\png.ico without comma and number after it.

But you can't directly use png file as icon. You'll have to convert it into ico file. You'll be able to find lots of web service that helps you for it.
