Not replace "src" with actual value.

[rscouto]

Hello tuupola,
I have a problem in my solution, I use Jquery Mobile and Knouckout and I use your plugin for load image of user logged, but when user make logoff I set value of attributte "data-original" for empty, and image "src" for default value, after other user make login the image load is of previous user.

I will hope understand me!

Hi tuupola.
The problem is in lines (115 and 100) of code you use command $self.data, this command use cache in my project changed this command for $self.attr("data-" + settings.data_attribute), and working perfectly. Please can you analyze my solution?
Thanks Big hug!

+1 @rscouto! I had the same problem except for a different use case which was setting the data_attribute to the appropriate image based on srcset values. When resizing the window the original image would be displayed even though the data_attribute had the new image. Now with your fix, it's all good. Well, I had to add trigger("scroll") to get things to work.

Ok I can confirm that this seems to have fixed a problem I had as well. The exact diff I used with version 1.9.5 to implement this is:

This seems to fix a recurring issue I've had where with a very large number of images, or when I'm dynamically swapping images in and out, they would sometimes not load.

Fixed in 1.9.x.
