A kodak pulse server simulator that will allow you to show the content of a picture rss feed. This is based on the work of Hajo Noerenberg and the proof-of-consept server. I've just adapted the code to download images from an rss feed.
The standard Kodak service allows you to send send images to the frame. But it does not allow you to limit the number of photos to say the latest 10 photos. After sending a lot of photos to the picture frame the new photos kind of drown in the number of old photos.
This is not for everyone. You will need an Apache Web Server, and control of your dns/firewall.
This might not be good for your frame. This is still kind of experimental and you should know your way around apache configuration and dns/firewall configuration. The solution turned out very good for me, but I take no responsibility for your picture frame and the damage this may do to it.
The installation procedure is written from memory after doing a lot of trial and failure. It might not be accurate. If you try it and find any error or other improvements to make the job easier, please let me know (or send a pull request).
This is what I did on my Ubuntu Server. It might be different on your system, but it still might push you in the right direction.
a. Generate a ssl certificate and install it in Apache webserver
openssl genrsa -des3 -out server.key 2048
openssl req -new -key server.key -out server.csr
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
openssl rsa -in server.key -out server.key.insecure
mv server.key server.key.secure
mv server.key.insecure server.key
mkdir /etc/apache2/ssl
cp server.crt /etc/apache2/ssl
cp server.key /etc/apache2/ssl
b. Create a site to handle the kodak trafic: at /etc/apache2/sites-available/kodak-pulse
<VirtualHost device.pulse.kodak.com:80>
ServerAdmin webmaster@localhost
# RewriteRule /DeviceRest.* /kodak-pulse-picture-frame-server.php

Do the simular thing for handling https, referencing the previosly generated certificate
SSLCertificateFile /etc/apache2/ssl/server.crt
SSLCertificateKeyFile /etc/apache2/ssl/server.key
c. Install the project files in the /var/www/kodak directory. Remember to change $rss_url to your favorite rss feed. I've created a pipe to inverse the order of the pictures in a picasa rss feed and to limit the number of photos. See http://pipes.yahoo.com/pipes/pipe.info?_id=d378e12925ff63939c05ce3eda60a8f0.
You should add &max-result=999999&imgmax=800 to your picasa rss feed, to ensure that you don't miss any picture and to ensure that the resolution of the picture fit your frame. Otherwise the images will not look all that crisp. If you have better resolution you should change the last value to match your resolution, e.g. 1024.
device.pulse.kodak.com
www.kodak.com
How this is done depends or your firewall/router, so you're on your own.
The old firmware did not validate the ssl certificate, which is what enables this hack to work in the first place. This security flaw seems to be fixed with the latest firmware(?), at least I cannot get it to work. Luckily for us, the old firmware is still available for download and by telling the frame to download the old version it should (e.g. the "update" file). I did this by downloading the file manually and and redirecting download.kodak.com to my server and hosting the file there, but I don't thing that is really necessary, so I left if out of the installation instructions.
This step is obviously not needed if you have not upgraded your frame and have the old firmware all ready.
Go into the picture frame and do a check for an upgrade. If everything is set up correctly the frame should check www.kodak.com/go something, which is in fact redirected to your server and hitting the update file, which will trick the frame into believing that the old firmware is in fact an upgrade. The frame will start the download process and after a while it will be done and ready to hit our very own server.
Now, just boot your frame and see your rss feed. You might have to reset your frame to factory settings (keep both buttons in the back pressed at the same time). You should accept the settings suggested on the start page (with an emailadress and stuff).
Use the rss feed for the dropbox album in picasaweb. Use the above mentioned pipe. You can configure picasa to accept emails sent to a dedicated mailaddress, and put attached photos in the dropbox album.
And voila, you have gone through all this trouble just to essentially have the same solution as Kodak provides, only that you now have the possibility to show only the latest pictures. If only Kodak would add this functionality.
