Using Exif to extract thumbnail images from jpg

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Using the Google Maps Export function
2.
3.

What is the expected output? What do you see instead?
It would be cool if the kml that is generated could refer to a thumbnail
image for the jpg instead of the full size image.  You could use exif to
extract the thumbnail image from the images as an optional setting.

What version of the product are you using? On what operating system?
0.92 Windows

Please provide any additional information below.
Currently I use:
exiftool -b -ThumbnailImage -w _thumb.jpg *.jpg
to extract thumbnail images and then upload them to a webserver and
manually modify the kml to refer to these thumbnail images

Hello John,

I guess you talk about the doc-web.kml.

It was Ok with my data (I export pictures with Picasa to the default 1600*1200 
and so
the pictures are quick enough to load) but it is definitely a problem for big 
size
pictures.

Then yes you're right and it is on top of my todo list.

Thanks for the feedback !

I had some issues with Exiftool concerning the batch thumbnails (with my data 
on a
Win XP box I lose one thumb each 10 to 20 pictures). Not sure why.

Anyway I use now the Python Imaging Library and it's fine (I also create a 
"thumbs"
folder).

An example of the result:

geo%2F29Apr07%2Fdoc-web.kml&ie=UTF8&ll=48.520925,8.146706&spn=0.102329,0.233459&
t=h&z=12&om=1

It is in the SVN and I'll make a build soon (this week-end)

Thanks
