After struggling for weeks with sharing a folder, I finally stumbled on the solution. I added the AOL email address for the recipients and it worked. Even though Xdrive allows you to enter a non-AOL email address for recipients, those don't work for sharing. They must be entered as AOL email addresses.
Another glitch is that this forum login has suddenly decided not to accept my screen name. It will only allow me to login by adding "@aol.com" to the screen name. Now if I could only figure out how to hide my screen name from spambots that might scan this forum....

Re: Have the devid and have it
Hmm, "custom images" - does this mean you're using the XML API? If so, what response are you getting? You need to use the XML API if you want to use custom images.
Can you post the exact code you have in your web page? (you can cut your devId if you'd like for security, or you can send the info to us in the dev.aol.com Contact form).
