Read/Write Permissions for all users and all objects in Users:Shared

Question

Hi:
I am using an application called "iView" to manage my image files. When importing images from my camera through that application, it creates a folder with the current date. The root folder is "Users:Shared:Images", so that everyone using our Mac can access the files. However, the files' permissions are only read/write for the user who downloaded the files (typically me), but I want everyone to be able to edit and delete files. Of course I can change the permissions manually, but there has to be a better way. (In addition, changing the permissions manually afterwards causes Time Machine to backup the files with the modified permissions again).
What do I have to do?
Thanks in advance.

That is the way that permissions work. If you are the owner of a file and want others to be able to read and write it, then you have to give them the permission to do so. To automate this, you can attach a folder action to the shared folder, for example:
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFDDFF;
overflow: auto;"

on adding folder items to ThisFolder after receiving AddedItems
repeat with AnItem in AddedItems
tell application "Finder" to set everyones privileges of AnItem to read write
end repeat
end adding folder items to
</pre>
