Hide the form using css display instead of visibility

[codaxe]

The visibility attribute keeps the element in the DOM flow and can cause UI artifacts.

I had the same probleme,
the solution is to add an width:0 ans height:0 in the .js file Line 142
replace:

var formHtml = '<form class="' + that.id + '_imgUploadForm" style="visibility: hidden; ">  <input type="file" name="img" id="' + that.id + '_imgUploadField">  </form>';

by

 var formHtml = '<form class="' + that.id + '_imgUploadForm" style="visibility: hidden; height:0; width:0;">  <input type="file" name="img" id="' + that.id + '_imgUploadField">  </form>';

The issue with display:none vs visibility:hidden is the compatibility with IE9 and EI10. I agree with your assessment, however we have decided to not merge this request based on the know compatibility issues.

I will leave it open as a reference for others with the same issue. Thank you for your contribution.
