//READ ME. NO REALLY, READ THIS
//Anything written using "//" is not actually part of the code. These are called comments and don't affect anything
//Usually they contain notes about how the program works.
//Hopefully this should be simple enough that someone without code experience can operate it
//
//Note: Not all parts of this program are guaranteed to work. I've tested everything as best as possible, but
//it is difficult to do without being able to access the heavy load page whenever I need it
//I also can't guarantee that it works on all systems in all browsers. I hope it works for your system,
//but I don't have the means to to test everything
//SERIOUSLY. READ THAT.

    //MORE THINGS YOU CAN MESS WITH
    //This area contains a giant list of images that the script will pull from
    //The basic format is:
    //image[num++] = {srd:"URL",width:x,height:y,text:"phrase"};//Comment
   
    //"URL" is where on the internet you can find the image
    //It should start with either "http://" or "https://"
    //And end with something like ".gif",width: ".jpg",width: or "png"
    //Those are image types and will work with this script
    //If it ends with something that is not an image type such as ".html", ".htm",or ".php"
    //You will run into trouble
   
    //"x" represents how wide the image is. If you set this to something different than the regular resolution of the image it will stretch or shrink it as appropriate
    //"y" represents how tall the image is. It works the same way as x. I recommend not setting y above 400, but its up to you
    //If you set x or y to something other than the default, remember to scale the other appropriately or your image will be distorted
    //If you change x use the equation "new y = ((new x/old x) * old y)" to find what the new value for y should be
    //If you change y use the equation "new x = ((new y/old y) * old x)" to find what the new value for x should be
   
    //"phrase" lets you customize the text message that is displayed
    //This only works if custom_text is set to true
    //If you decide to insert your own phrases, quotation marks will not display properly
    //If you wish to make a " appear you need to put \" in place of it in your phrase.
    //HTML inserted into the phrase -should- work properly, <h2> and <h3> should be predefined by the webpage
    //You're going to want to include <h2></h2>, or <h3></h3> around your phrase to make the formatting work
    //DO NOT PUT IN A BLANK PHRASE
   
    //"//Comment" is a note to yourself about what the image is
    // The URL is a difficult way to remember it, so this will help keep track of everything
