Need help uploading photos onto my wordpress site to an existing gallery

This is a really basic project but I just have not had time to do it. I need someone who is familiar with wordpress to upload photos into my existing gallery (www.kalulukids.com). In addition, I need you to create another page for sarongs...and to upload a few photos there. If you are familiar with photo shop, this will help too since you may need to resize the photos. If you see the gallery as it stands now, when you click on a photo, it gets bigger. If you have any design skills and have some recommendations as to how to make the gallery look appealing, I would love to hear it! In total you will be uploading about 20-30 photos.
