There are not much difference between png and jpeg. It all depends on how they're encoded. png with transparency will get bigger. The inconvenient with random is that when it finds a randomly choosen post for the first time, it will generate the thumbnail. So, it can be often if you have a large number of posts. Other than that, it shouldn't use a lot more resources than other. How many posts do you have on your blog? If you’re using sharpening or rounded option, it will certainly increase memory usage.

How many posts do you have on your blog?

Keep in mind that, with gd, a jpeg uses an incredible amount of memory. A 1000×1000 image can use from 8MB to 15MB or more depending on quality, encoding,…and I guess you’re using high-quality picture. If memory is the issue, I guess you’ll see only rather small picture appear." Do you mean the generation of thumbs from fairly large pictures will be quite cpu/memory intensive? I was using pt-random on the sidebar with about 3 150x125 thumbs (rounded corners,png) linked to posts and incidentally in the month of Feb to early March, my site went down about 3 times, due to high server load and needing manual reboots. I can't be sure that it's the thumbnail generation that's causing this, but I took down the widget for the time being , regrettably so.. I really loved the random thumbs. I wonder if there's a way to reduce the load, is it the png thumb using more resources? Are jpgs better? “Unfortunately, Post-Thumb uses gd and no imagemagik which is much less resource consuming.

1.No, it’s not normal. When you edit a post, the image to thumbnailed should be selected then and the thumbnail created first time page is refreshed. How much memory do you have available on your server?
2.See above.
3. This one’s weird as draft shouldn’t be in the database…
