Impressed that you were able to get your "noob" comment in.. You must be proud.
It takes me 10 seconds to open thumbnail view at other hosts, and click the few images I want, and get my code.. I dont see how saving to a .txt file is saving me significantly less time. I also use html code on my blog site.. Being that every other host I have used, lets you view images by thumbnail, it seems like a reasonable question. I am usually done needing the codes after posting them to all my locations, so there is no need to "store" the codes after that..
I post one image at a time on certain sites, using straight link to the host page. Later I go back and grab a group of them to upload as sets to other sites. So that is 3 different ways that I link images(bbcode, html, and regular link).. Is your suggestion saving me that much time??
