Kind of grinds my gears, too. The official SkyDrive app can only be used to upload one stinking file at a time (doesn't utilize the new "multi-select" functionality of WP8). If you want to use it to upload photos to a new folder, sign into the app, click the three dots in the corner, create a folder, then when you want to add files, select the plus symbol while in the folder and either choose a file or select the camera icon to take a picture and send directly to that folder. Again, even taking the photos, you will have to re-select the option to take a new photo one at a time, over and over. The official SkyDrive app blows, and the native SkyDrive functionality - while pretty good - could use some tweaking (such as choosing a folder, amongst other things)
What you're going to want to use is an app called "Camera Roll Sync". There may be others, but I stopped looking once I found this one. You can choose a folder to sync your files to on your SkyDrive, and then you choose a date that tells the app to sync all photos after that date. Sounds like it's exactly what you need... not exactly what you'd want if you use the app after you've taken unrelated pictures destined for another folder (since there's no "end date"), but maybe something else exists out there that does this. Oh yea, the actual main purpose of this app is to upload the full quality and resolution of your photos to SkyDrive... the file sizes I've seen are even larger than those uploaded using the native "highest quality" option on WP8 - leading me to believe that the phone still actively compresses to some degree, which is a shame.
