trying to fix picasa/blogger photos

Sorry I have not posted a new blog post as promised... I was all set when I realized my picasa account (which manages blogger photos) was at capacity. I guess I have been uploading the photos wrong (or too large). I have gone through my account and deleted duplicates but this only saved me about 15%. I need to go back and resize the photos I have already posted (400+ photos). I am hoping that it will not take too long...I will research and see if there are some tricks to do this quickly and automatically. So stay tuned! Either way I do have some free space so I can at least get one or 2 posts up soon. TN
