For posting pictures to CiC, I recently switched from using the TinyPic upload method to using the Publishing Services in Lightroom. I publish to Picasa Webs/Google and then get the link and embed it in my post. I use a plugin by Jeffrey Friedl which can be found HERE. (He also has them for other services such as SmugMug, PhotoBucket, etc.) I chose Picasa because I share most of my pictures with family through Google+. Many times, photos that I'm posting on CiC are the same ones I'm sharing on Google so by using this method I only have to upload to one place and it's much more automated. I have Smart Albums set up for different types of photos, i.e. Wildlife in Colorado, Wildlife in Texas, Landscapes in Colorado, etc. The Smart Albums key off of keywords such as wildlife, landscape etc to put them in the right folder. They all require the keyword Google. Since I have the names of all the G+ Communities and CiC as child keywords under the parent keyword of Google, then by using those child keywords I can keep up with where I have posted my photos.
There are only 2 disadvantages that I've found so far to this method. First, although the metadata is with the picture on Picasa, it does not carry over to the post on CiC. And second, if you modify a picture, it automatically gets put in a queue to be republished and it replaces the original picture. This means that if you've posted a link in CiC to a picture and people make comments which lead you to reprocess, the original picture will be replaced with the update causing the original conversation to not apply to the picture now showing. So to keep this from happening, you need to make changes to a copy or virtual copy. This is the way it works with Picasa and links from CiC. I'm not sure if other publish services work the same. I know that if you share a post in Google+, republishing a modification later does NOT affect the previous posts.
Anyway, I don't remember seeing much conversation about how people used the LR publishing services so I just thought I'd share what I've found so far. I think it's pretty slick.
