Regarding images there are some things you can do to make this bric run even smoother:
Use reasonably sized images
The biggest performance lag comes from using really large images and letting the bric script scale them down for you. This might work OK in your local environment, but it can have great effects for users with less optimized setups and slow internet connections. Always scale down your images to a reasonable size and use jpg for compression.
Optimal image sizes are:
- Landscape: 900 x 600 pixels
- Portrait: 450 x 800 pixels
Compress your images
Another good procedure would be to compress your images prior to uploading. There're several image compression software available for the Mac, I use these:
