Javier:
Most unlike anything I have seen attributed to WF, either in the flesh or in the two books. Knobbly colour schemes from the 1964 WF trade catalogue page reproduced in Evans (the Museum of London book) were:
Streaky Brown, Streaky Green
Blue, Green, Ruby: (cased in clear crystal).
There may have been one or two other colours, but nothing deviating significantly from these two basic styles.
If you download IrfanView, all you need to do is:
1. Drag & Drop your camera image from Windows Explorer or My Computer into IV, or do it via the File menu,
2. Select cropping area using your mouse,
3. Edit - Crop Selection,
4. Image - Resize (keep Preserve aspect ratio ticked) to no more than w400 and h300 pixels,
5. File - Save As - try Save Quality at 70%, then adjust this until you have an output file around or less than a dial-up user friendly 30Kb in size. With a plain background you should be able to get closer to 20Kb.
Once you have mastered that it is a simple job to upgrade to using clickable thumbnails of around 100-120 pixel dimensions - a really user friendly 2-3Kb in file size.
I hope that helps, Bernard C.
