@antp:
You said there is no need to point the "wonderful" ads of ImageShack as you'll use a batch script to replace them by backup images. But until what date did you make these backups? Will there be a specific picture (saying "No more picture available", or something like that) for deleted pictures without backup?

These ads are all but subtle, all the more when appearing like hail:

I was doing backups until I copied all images to our server, around February 2012.
Those that are still on imageshack are:
- those posted after that
- those lost by imageshack or unavailable at that time (and the next months)
- the PNG images (I still have to copy & convert these)

I hope your backups will "cover" most of these ads, they're boring.
