Change estimated image size moving image size slider

[andybuki]

Hi, if i move the image size slider the estimated image size stays the same.
Do you plan to adapt it?

Sorry, yes, this was a bug that I introduced in an earlier change. The estimate should now update whenever any of the values that influence the file size (scale, choice of pages, manifest itself) change.
