Can't find Skype photos captured on Skype on my MacBook Air
OK, I did the search and found it in most peculiar place one can think of.

This is on my MBA with 10.9.2.

~/Library/Containers/com.apple.ImageKit.RecentPictureService/Data/Library/Images/Recent Pictures


You will find two types of image files there -- TIFF (thumbnail) and standard .png

The .tiff are converted by Skype to a profile pictures, the .png are the originals.

Extra information:

If you need frequent access to that folder but do not want to remember its complicated location


Right click on the folder (Recent Pictures)
Click on Make Alias
Drag the Alias folder to your desktop (you can rename it to what you like)
