Step 2:
Install Webshots
Go to webshots.com and download your webshots to the desktop. Open it with wine and go through the next-next windows.

Install it in “C:\Program Files\Webshots\”

Step 3:
Make script
Go to “Applications –> Accessoires –> Text Editor” and paste the following code in it:

#!/bin/bash
cd /tmp
echo "$1" > wbsht
sed -i -re 's/\//\\/g' wbsht
argument1=`cat wbsht`
argument2=`echo z:`
argument3=`echo -n $argument2
echo $argument1`
rm wbsht
wine "C:\Program Files\Webshots\Launcher.exe" "$argument3"

And save it.

Step 4:
Download your photos.
Go to Webshots.com and download your photo. Firefox asks you if you want to open it, or save it. Choos open ands click ‘browse’ and choose the script you’ve saved in step 3.

Step 5:
Install UWC.
Download UWC here. And install it just like webshots.

Step 6:
Run UWC.
Go (in UWC) to Conversion –> Batch conversion. Select ‘+folder’ and choose ‘”My Documents –> Webshots Data”.
Select a destination folder, and click let’s convert!

Since an update webshots doesn’t work anymore. Here is an workaround (run this in a terminal):

cd ~/.wine/drive_c/windows/system
wget http://www.dll-files.com/dllindex/download.php?mfc42download0VMfWEdMdO -O mfc42.zip
unzip mfc42.zip
rm mfc42.zip
cd ~
