export to folder p. 117
JPEG files use lossy compression. That is, the higher the compression you select, the more image quality you'll lose. (By comparison, compression algorithms for TIFF files are lossless. That is, no image quality is lost; the files are simply made smaller.) If you're exporting digital photos that will only be viewed onscreen, you can safely apply much higher compression before its effects are evident onscreen. However, if you intend to print the exported files or edit them in another program, you'll want to keep compression to a minimumuse a JPEG setting close to 100%.If you've previously exported images from the current folder, you can select the previous destination folder. Doing so prevents the creation of a new subfolder.

Gift CDs reflect edits you've made in Picasa. The resulting images can be viewed in any programnot just Picasa.When creating a Gift CD, Picasa tells you how much data will be written and the number of discs required. A blank CD holds approximately 650 MB. If you're over that amount, you can pick a smaller image size or reduce the number of images by selecting fewer folders.
