Remember the old days of uploading a file or attaching the files. There used to be, why the good old days, even in blogger the same type is available.There is a check of maximum 5 images, and to get the upload box we need to click the "Add another image" link again and again.
I checked Picasa and was so happy by it, there is a drop pane where we just need to drag the images that need to be uploaded, rest is taken care.
The solution works well here as here we have multiple images that needs to be published on the internet.
Hats of to Google for this feature. I like it and it solves the problem so well.
