TIP 143: Using Large JPEGs as Smart Objects


Ask any Web designer if you should ever recompress a JPEG image and they're likely to roll their eyes, stomp their feet, and snort out something like, "Absolutely not!" Well, that was true a few years ago, but modern digital cameras store very high-quality photographs in the JPEG format. The fact that a JPEG image can be high-quality contradicts most designer's expectations, but the fact is that JPEG doesn't necessarily mean it's had all the quality squeezed out of it.

All of this means it's perfectly reasonable to use a high-quality JPEG image as a Smart Object source file even though, technically speaking, the image will be compressed twice: first by the camera and then by GoLive. To make it easier for GoLive to use large JPEGs as Smart Object sources, there's a new application preference that controls how Smart Objects are handled. Choose GoLive > Preferences (Mac) or Edit > Preferences (Windows) and choose the Smart Objects section of the Images preferences (Figure 143).

Figure 143. Control the size threshold of JPEG Smart Objects in the application preferences.


The setting that automatically converts large, Web-friendly images to Smart Objects is enabled by default. The feature kicks in when the source image has a dimension larger than 1,000 pixels. If you want to increase or decrease the limit you can, but 1,000 is a good default because it lets you use images less then 1,000 pixels wide as full-size gallery images but will convert anything larger to a Smart Object. To see the feature in action, drag a JPEG with a dimension greater than 1,000 pixels (such as a JPEG from a 4-megapixel digital camera) into the Layout Editor.
