Thanks for following my blog! I'm following you now, too. As for uploading multiple pictures... The easiest way I have found is to upload them into Picasa. You can add multiple pictures at once by holding the CTRL key. Then when you have an album saved in Picasa with the pictures you want for a specific blog post you can insert as few or as many pictures at a time into your post. One of the options when you click on the icon to add a picture to your post is if you want to get the picture or pictures from Picasa. When you click on that, all your albums will appear and you click the one you want. Once you do that, you just click on the pictures you want to add but you don't have to hold the CTRL key. When you click on the pictures it will highlight the ones you are adding. Hope I didn't confuse you more! If you have questions, feel free to ask!
Clicking on CTRL and holding that button down while selecting all my desired photos works for me.
