Just a heads-up to let you know that images like the comic book covers can be made into much smaller files without making the images any smaller or losing any pixels.

A 10:1 storage-size compression is often possible without significant quality loss or any change in ease-of-use. The JPEG file standard incorporates a number of different compression tricks, not all of which are invoked when the files are first created. I'm not sure if when those files are included in a .pdf document, the compression is carried over. It might depend on what you're using to create the .pdf, too.

The advantages of smaller graphics files are twofold. One, it loads faster for the reader, and being smaller, there are less problems and retries. And Two, and this is probably more significant from Erin's point of view as a site owner, it reduces the amount of bandwidth needed to deliver the pictures. Less bandwidth use can mean improved server performance and lower comm bills.

If you'd like me to demonstrate what this form of graphics file size reduction looks like, please feel free to email me a few images (as separate raw image files in whatever original form they were created, and please email each image separately) to pippa.kingsley [join these with an at sign] gmail.com and I'll return the results to you, along with complete instructions as to what I did. The only form I can NOT edit the images in is as a .pdf, as I don't have the right tools for that.
