Desktop Pictures Problem- qtimageserver

Last night, I decided to change my desktop picture. I set it to: Change Picture every 5 seconds. Well, this morning, I noticed that my system was running incredibly slow. I knew that something was wrong. So, I used OnyX to clean up some caches, and it optimized my system. Then, I booted from my OS X disc and repaired permissions, but my system was still running very slow.

I went to Activity Monitor, and discovered the problem. A process named “qtimageserver” was hogging up 60% of my CPU! I have never heard of this before, so I Googled it, and found my answer. “qtimageserver” was really the desktop rotation process. So, I go to my system preferences, and uncheck the checkbox for the rotation, and what do you know, my free RAM goes from 5% to 60%, and the fan noise drops.

The pictures that I was using were actually Adobe Illustrator files. In case you don’t know, Adobe Illustrator files are pretty large files. So, I narrowed down the problem, and this is what I suggest to you; do not use the image rotation option if you are using large image files, because it can really make your system slow down.
