== Result list thumbnails and how to create them

Recoll will display thumbnails for the results if the images exist in the
|
|
|
4 |
standard location ('$HOME/.thumbnails' or '$HOME/.cache/thumbnails' depending
|
|
|
5 |
on the xdg version).
|
|
|

But it will not create thumbnails, mainly because it is very hard to do
|
|
|
8 |
portably.

Thumbnails are most commonly created when you visit a directory with your
|
|
|
11 |
file manager, but visiting the whole file tree just to create thumbnails is
|
|
|
12 |
a bit fastidious.
|
|
|
13 |
|
|
|
14 |
One simple trick to create thumbnails from the recoll GUI is to visit the
|
|
|
15 |
parent directory for a result by using the _Open parent document/folder_
|
|
|
16 |
entry in the right-click menu.
|
|

You can also find tools for the systematic creation of thumbnails for a
|
|
|
19 |
directory tree. Three such tools are discussed on this

Also please note that no thumbnails can currently be generated or displayed
|
|
|

for embedded documents (attachments, archive members, etc.).
