Your question is not 100% clear. Typically when you scan any picture you scan "to disk" meaning the file is stored as a bitmap, in the format of your choice, at the scan resolution and color depth settings of your choice wherever you choose on your computer / hard drives. The Epson Scan utility is perfect for this and is included.

If you mean scan directly "to optical media / burned CD or DVD" then, no, you would scan your files to your compute'rs hard drive first, then you could burn a "disk" (CD / DVD / BluRay) with whatever pictures your have assuming you also have burning software (available free online) and a CD / DVD / BluRay burner with some blank media.

You can also scan to make quick copies a la "to printer", send directly to OCR software to convert scanned text to editable text files, etc.

I will do my best to answer this completely. You can load up the scanner bed with as many photos that will fit physically. The Epson scanning software allows you to define multiple rectangular regions so you can define multiple photos at the same time. In other words, you do a Preview pre-scan, draw your selection rectangles around each photo you want to scan. In "normal" mode, when you click scan only the highlighted selection rectangle in scanned. This works surprisingly well. To scan multiple images at the same time you need to CTRL-click (on WIndows, not sure about Mac) each selection rectangle so multiples are highlighted at the same time (all dashed line selections), then click scan. This way you can scan as many photos as you can arrange at the same time, in the same pass. Keep in mind the scanner itself actually makes multiple physical movements / passes.
