IDEA: Drop Zone for Web Images
lifeweaver:
That is much better.
There seems to have been a change that has crept in, in that the filetype is now JPG it was jpg
Also the default datestamp, has Minutes omitted ;)
It may also need an error trap.
If you create a second event but don't change anything from the default it will throw an Invalid Option. This then cause a problem when you try to return to the config with a further error Invalid Gui name, and again on exiting.
I can use it with Firefox for what I need, but will look at IE11 again and the security issue when I get a chance

Not sure about this one, I'm able to download .jpg and they stay .jpg, can you check the actual image on the website and verify it isn't named .JPG?
I added some error checking, and fixed the cause of the error popup.
I've changed the default dateFormat, the original post didn't specify minutes. => 'PREFIX YYYY-MM-DD_HH-SS SUFFIX'
Reminder: you'll have to update the timeFormat for all your created dropZone.

Your right, I must have missed typing minutes in the original spec :)
The JPG jpg issue is as you say. I must have hit on some images where everything was JPG which made it appear that a change has happened.
Can you repost the code, it didn't add correctly and now has emoticons :)
lifeweaver:
Just modified it, I think there is a limit to how much text can be posted in one post as the preview looked correct but it kept cutting off some.
magician62:
Works well. I like the create /update change. It will save 4 clicks for every image, especially when you are almost certain there will be a name conflict
You should find a small donation of my appreciation. :)
lifeweaver:
Thanks!
