If you have any problems with copying and pasting let me no on this thread.
I find having the generator link in my favourites helps.I also have the image showing on my istock page that i wish to add the same type of image too.
Then i just press the link for the generator in my favourite,fill in the generator,copy and paste then just press the back button and your istock page appears and just scroll down and edit file information and copy and paste the html code into the box and press ..save.
