Images not displaying for me

Questions
1

I have something like this in my template

					<div class="profile">
						<picture>
							<!--[if IE 9]>
							<video class="none"><![endif]-->
							<source srcset="@CurrentPage.desktopImage9" media="(min-width: 1100px)">
							<source srcset="@CurrentPage.mobileImage9" media="(min-width: 100px)">
							<!--[if IE 9]></video><![endif]-->
							<img srcset="@CurrentPage.desktopImage9" alt="@CurrentPage.altText9">
						</picture>
					</div><!-- /.profile -->

					<div class="biography">
						@CurrentPage.Name9
					</div><!-- /.biography -->

however when I take a look at my page, sometimes the images show and sometimes they don’t. this varies upon refresh. I am using Articulate Cropper as an editor to show these images, however i had the same problem when I tried using Media Picker.

thanks
