Gallery Set up in wordpress

This project is to install, customize, and set up a gallery in wordpress. I need to have a gallery plugin, that has the usual grid of thumbnails on the page, and then when clicked, the image is enlarged. However, I need to have text underneath the thumbnail, and different text underneath the large image, and I have to be able to format the text in both places. I must be able to have line breaks, bold, and mailto links - both in the text below the thumbnail, and in the text under the enlarged image. There must be a way to have different text in the two areas, as well. I have fifty items that need to be loaded, in order. I have all of the images, named in order, and both sets of text for each image in a text file.
