Hi Craig Brown,
Yes, unfortunately this is a known issue. We will try to get this issue resolved as soon as possible.
As, for your second problem, there are two things:
a) you are getting the syntax error; in the alt tag you are missing the closing "%>" tag
b) this however, won't help you a lot. What you need to do is actually following (as we do not store the url in the image field, but information about the image from the libraries module)
<sitefinity:AssetsField id="bioPhoto1" runat="server" DataFieldName="BioPhoto" />
make sure you include the Telerik.Sitefinity.Web.UI.Fields namespace (with tag prefix "sitefinity") for the above code to work.
A bit of background on the AssetsField. It works with single document, multiple documents, single image, multiple images, single video and multiple videos. The control will autoconfigure itself based on the type of the field designated through the DataFieldName.
Hope this helps.
