Unhandled exception when saving after pasting image

[Bone008]

System information:

• Windows OS version: Win10
• ImageGlass version: 7.6.4.30 Portable

To Reproduce

Steps to reproduce the behavior:

1. Copy a base64-encoded image string from browser or some other raw image data (e.g. from Snipping Tool, Photoshop, ...)
2. Open empty ImageGlass without "Show welcome picture" enabled.
3. Hit Ctrl + V to paste image.
4. Hit Ctrl + S to try to save image.

Actual behavior:

Unhandled exception occurs:

System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string.
Parameter name: startIndex
   at System.String.Substring(Int32 startIndex, Int32 length)
   at ImageGlass.frmMain.<mnuMainSaveAs_Click>d__133.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

Expected behavior:

Save dialog should open and allow saving the image.

Additional context:

Works fine when "Show welcome picture" is enabled in settings, most likely because the filename "default.jpg" is then present. Without it, the filename is empty, probably what causes the exception :)
