Hitch always gets my name wrong.
If people have a hard time remembering it, I just say "Texans with 2002 in the middle".
I believe these topics were the ones Hitch was mentioning:
Here is an example I point to to show off the differences between JPG/PNG (in this specific case, showing off images of Text/Tables):

Here is an example of how I handle images of complex Math Formulas in EPUB. This is my Formulas to PNG Tutorial (you can see the tiny size of the PNGs, while the resolution is high):

And this is the example I point to to show why PNG is superior to JPG when dealing with ARTIFICIAL images (charts, graphs, screenshots, ...) or images with very few colors (line art, clip art, business logos, ...):

I personally use this program called ScriptPNG, which is a very easy drag/drop way to compress PNGs. (There are also powerful commandline tools, although I would say those aren't very "noob" friendly).
Depending on the images, using PNG can get you to a filesize <50% the filesize of the equivalent JPG, while at the same time, achieving much higher quality (PNG = lossless, JPG = lossy).

It could be painful, but sometimes, it is best to do over, and start from scratch, making sure you do it PROPERLY, to save yourself many headaches down the road.
For example, I try to now tackle formulas in a way that I can easily generate whatever resolution I need in the future. Higher resolution device comes out (which they will). BAM, It takes me about one second to use the commandline and generate completely higher resolution formulas, since I laid all the proper groundwork.
If you handled it by painstakingly generating tiny thumbnails, all of a sudden, you have pushed yourself into a corner when you want to release a new edition. (See my Formulas Tutorial).
Similar thing I always stress when people insist on by saving the caption INSIDE of the image itself, instead of using CSS and letting the chips fall where they may. In the short-term, sure, the caption stays with the image, and it looks "ok", but in the long-term, the higher the resolution the devices become, the worse and worse that caption text will look, and it won't just be a simple CSS fix. You will have to redo all of the images!
