This is a little bookmarklet for you. Select some text in a page then run it. It will open a new window {selected text}.jpg.to.

   javascript:(function(){var A='';if(window.getSelection) A=window.getSelection().toString();else if(document.getSelection) A=document.getSelection().toString();else if(document.selection) A=document.selection.createRange().text;A=A.replace(/\s+/,'-');if(A===''||!/^[a-z0-9_\-]+$/i.test(A))A='try-again';window.open('http://'+encodeURIComponent(A.toLowerCase())+'.jpg.to');}());

not tested at all.
