I've been working on this modifcation for a few customers. Basically I'm adding charts/graphs into the "Site Log" module, refreshing the dull grid with some really snazy interactive flash charts (powered by google). Currently I'm targetting DNN5 rc2, the modifications do not require any recompiles or dll replacements for DNN5 and should work on older versions with a core recompile. For DNN5 just extract the zip into ~/DesktopModules/Admin/SiteLog and overwrite the files.

Here are the files, and a live demo site. The charts still need some minor work, everything but the first two and last reports are wired at the moment.

I'm also getting ready to release the photo gallery module that is configured on the Home Page of the demo site, it will also be a free release and it pulls the images out of picasa/flickr via providers.

What browser are you using? And do you get any javascript errors?

The photogallery module is pretty sick, I'm quite proud of it. I forget what the page limit is, but I think it's 1000 pictures for picasa. I'd have to check for flickr. Yes the photosize is completely customizable (however flickr should really add more sizes into the api). You set columns/rows in the module settings, and that's how many items will be displayed. The Lightbox control is also a provider, and I've got 3 more in the process right now. Hopefully I'll get betas posted of both controls very soon. 

I'm working on adding at least one more chart type into the mix, and I'll post the files later today.
