MRmarco,
Sorry I can't help you with the bond but I may be able to make your life a little easier when trying to upload images that you've scaned. I shared your frustration with reducing image sizes under the 100kb limit for uploading to SCF until I saw that several members had suggested using an online media hosting service.
I opted for the free hosting service ImageShack (
http://imageshack.us/ ) and am glad I did. I scan my item at 600dpi, open in IrfanView (the program downloadable at the SCF's "uploading photos" tutorial), and crop the image. Then I upload the file to my ImageShack account which is set to resize all uploads for viewing on a 15" monitor.

Once uploaded, I copy the direct link address into memory, and paste the link between the commands [img ] and [ /img] that are automatically generated when selecting the insert image button in the format bar of the "reply to post."

That process has saved me time and frustration when including images in my posts.
If you use the SCF's search function, you can find other options to consider.
Steve
