I use WikidPad for organizing my notes, in more complex structures for a more structured approach, but for the purpose of documenting ideas or facts.  WikidPad, can't copy the images from the text I capture automatically, but later I can add the pictures I select to add to the document with copy and paste.  In this case, WikidPad archives the image in a folder relative to the wiki document.  Therefore I can always copy the documents (are text with a light markup interspersed) with its acompanying folder.  Every image has a relative reference in the text.

This approach can be used in Cintanotes, which is light and avoids the incredible amount of figures and icons used in web pages, that for notes purposes are a drawback.

I like, also, the Ctrl-F12 approach, because leaves Ctrl-C free for a different purpose, allowing a selective note keeping.

My notes won't stay long enough in CintaNotes, because will be further processed.  Temporary notes, will be discarded.  Some notes will be transfered to WikidPad and the remaining notes, are for actions, than when fulfilled allows me to discard the note.

Therefore, Cintanotes is the first entry for the note taking process.  For being fully effective and light, must be preserved its only a database approach, with recording of images when done by the user or automatically for images above some size.  For simplicity should be restricted to raster images.

The notes, could reside permanently on CintaNotes or being transferred at will to a knowledge base or to an diary or log, through cut and paste.

Another element of great importance is the reference that CintaNotes attach.  Although is not a completely bibliographic reference, could be enough for most purposes.  Another important element is preserve the UTF-8 comliance.
