Thanks Victor. Fixed now in version 1.41.

I've released version 1.3.

Now, if you 'Allow Downloads' on your own Flickr account, then the AllSizes button will be added to a photopage, if it is not already present.

More information in the discussion thread. See this comment.

@Jeton - With the current release, the AllSizes button is not added to the photopage if it is not already present.

So, if the photo you are viewing does not have the button when you logged out, but does have the button when you log in, then the script will only be available when you are logged in. Is this what you are seeing?

There is something of a discussion going on at the main Flickr Hacks discussion thread about whether to add the button or not, and if so, what features to enable. Please feel free to join in with it: http://www.flickr.com/groups/flickrhacks/discus...

@adelic - Thanks for your message.
I suspect you are trying to view a photo where the owner has chosen to not allow downloads. The script now (at least, at the moment) doesn't let you view all the sizes of photos where the owner has chosen to disallow it. Please see the main Flickr Hacks discussion thread, as this has been discussed there.

@adelic - I think you're going to have to be a bit more specific than that. What kind of problem are you having?

All is working and up to date :)

- Note that I don't often check the comments on this page. For the latest, be sure to see the Flickr Hacks discussion page.

Thanks for your comments.

@M.J. - Flickr have just made some changes to their scripting which caused this problem. It is now fixed in version 1.116 :)
