Where's the option for a background image?
It is relatively easy to use a background image by setting the gallery's background opacity, the last parameter in rgba(), to something less than 1 (so that it is visible), such as:
backgroundColor : 'rgba(34,34,34,0.5)'
... and then changing:
... to something like:
<div id="juicebox-container" style="background-image: url('image.jpg');'></div>
Make sure that your background image is in the correct location.
For the Title and Caption, why did the font size scale change? In SV builder I used 18 & 12 as the sizes, now I need 4 and 2 in JuiceBox.
In the Flash Player in SimpleViewer, the font size was a pixel value. In the Mobile Player in SimpleViewer and in Juicebox, the gallery is HTML-based rather than Flash-based and the font size is on a scale from 1 to 7. Please see here for details.
If you set <font size="18"> in SimpleViewer, the Flash Player would display the caption at 18px but the Mobile Player would display the caption as large as possible (as it is a value greater than 7). Because of this difference, the font size attribute is ignored in SimpleViewer's Mobile Player.
The font size is configurable in Juicebox (as, unlike in SimpleViewer, there are not two different ways the value can be interpreted) but being HTML-based, the scale of 1 to 7 is used.
Also, being that Juicebox is HTML-based, you are no longer restricted to using HTML tags that are accepted by Flash so rather than:
<font size="4">Caption Text</font>
... you could enter:
<span style="font-size: 18px;">Caption Text</span>
Setting these options will get confusing; it would be nice to have a couple different preview options:
1) what it will look like on a website
2) what it will look like on an iPad
3) what it will look like on an iPhone
In order to see what your gallery will look like on a mobile device, go to 'Customize -> General' and set 'Screen Mode' to SMALL. For more information on Screen Modes, please see here. There is also an 'iPhone Simulation' demo gallery on this page.
Thank you for your other suggestions.
