Pixelpost

No, unfortunately, when you choose "replace" it simply uploads the photo as a new post, it doesn't replace it. Perhaps in the future that feature will be fully developed.

Jay, I was trying to leave a comment on the lightroom extension, but for some reason I can't, so I try it this way. I just discovered pixelpost and with the lightroom extension everything works like a charm. But...
If I export an image again from lightroom I get the option to replace the image (some of these images have been uploaded already). When I choose replace I will see that image as a new post in my pixelpost site and the old image is also still there, it seems the replace function isn't working.

Is this a setting somewhere?

I'm using LR 2.2 523352 on a Windows Vista machine.
