Maybe try uploading a few pages at first, so as not to overload anything.
Barry might be able to advise on how to squash it,
or might be able to display a moderately high res version that isn't too huge?

I have e-mailed Adrian to see if we can find a good way to get the files uploaded to somewhere. Then I can get them visible.

I now have a program for making photo's smaller in pixels.

We'll look forward to seeing them!
Many thanks, and Merry Xmas,

I have found a jpeg shrinker; also I could do a less pixel scan.

Warning, start of geek :geek: mode :roll:

100dpi will generally do, Greyscale also can cut down a lot especially if you can reduce the palette size (less shades of grey).

GIMP is a well known graphics program which works on a variety of operating systems.

My own strategy for scanning is to record everything at 300dpi with 24 bit colour and save the result as a PNG file. A set of such scans from a book or manuscript form a master copy for archival purposes. I don't edit these files at all except to rotate them by +/- 90 degrees as appropriate.

If the page does not contain photographs, my recipe for a more 'economical' copy is as follows.

I crop the image to get rid of edge effects,
convert to 100 dpi
convert to grey scale (desaturate) based on luminosity.
Use the colour editor to make the very light greys, white and the darkest greys slightly darker, but not completely black.
I then 'posterize' to reduce the number of shades of grey to 16 or 8
change the image to ' palette' mode
save as a PNG file with maximum compression. (this is a lossless compression.)

this will take a 4 - 6 MB image down to 60 - 100 KB, which I think is far more manageable.

If anyone is still reading this I would welcome any comments or questions. :geek:

Adrian,
Please, start uploading them, a page at a time if necessary.
You have a valuable resource there - don't fret about technical issues.
This may give Barry a bit of work with his jpeg shrinker, but at least means the documents are uploaded.
Then we can start playing the tunes, once we can see them.

John

PS Sorry, Barry!
