Both CDs and DVDs offer a means to permanently store photos for archiving or display.
Creating a permanent storage medium for your photos is often a desirable activity. CDs and DVDs both offer a similar means of allowing you to store and display your photos in a secure format.
Size
The biggest difference between CDs and DVDs is the storage capacity. CDs can hold 650 megabytes of data, and DVDs can store 4.7 gigabytes (4,700 megabytes). Dual-layer DVDs can hold 8.5 gigabytes. The number of photos stored on either format depends on the photo's own size, which is determined by its own quality and format.
Cost
Blank CDs and DVDs are similar in price. The only concern with cost is if you have a large collection of photos that you're looking to store you'll have to purchase many more CDs than DVDs to make up for the approximately seven times difference in storage capacity.
Compatibility
In older model DVD players, photo DVDs have had some compatibility issues during playback. Newer models, however, should offer the same abilities as CDs. Both are fully compatible on any computer as long as you have the appropriate drive.
