Need to Generate Thumbnails Help!

Question

What’s up guys? I'm kind of new to programming and I’m doing a personal project. On my Project website I want to generate two thumbnails 1, (111x82) and  2. (200x147). The source to generate the images is a URL, For example Http://www.mysite.com and later add a random string as a name then save the names to a database table and save the file to a directory on folder. I want to do all this inside a class. Can any anyone give me a hand?

 

Thanks

Juan
