Okay... With the memory bug again...
http://luckyshotphotos.com/test/index.php?album=flowers
It seems all 3 thumbnails were created instead of just 2 and 1 not loading..
(The yellow flower didnt load before with the memory problem)
Okay so it created a thumbnail for it (thats good!)
Except, it wont create a smaller size of the iamge itself (when you view it)
Ex: Click the yellow flower thumbnail and it brings you here:
http://luckyshotphotos.com/test/index.php?album=flowers&image=IMG_3828.JPG
Notice it doesnt make/show a cached file...
So I guess, SB, you are on the right track, you halfway fixed it

...right?
Edit: This is also the lastest nightly build, i manually downloaded class-load.php
