I have just found two interesting tools for designers:
1. www.myfonts.com helps recognize unknown fonts. You just upload your image, then the site will determine the right font for you.
I tried this site, sometimes it is good, sometimes it is not very correct. But anyway, it is a good site to visit for designers who wants to know fonts from a picture (such as SmartOSC logo).
2. Pdfhammer.com: This helps read PDF files. There attaches some edit functions to move pages within the pdf file.
So, if you have some time, check them out. I hope they can be useful for you.
