Topic: Background Color for Main Image

Hi, the images in my gallery are all transparent PNGs that must appear on a white background.

However, the color behind the main image is black & I cannot see where to change this.

I have changed settings 'Background Color', 'Expanded Background Color', and 'Background Image'

You can see what I mean here: https://i.imgur.com/Iy49rAH.png

Please advise.

Re: Background Color for Main Image

When JuiceboxBuilder-Pro resizes images for a gallery, it converts PNG images into JPEG images and any transparent regions are rendered as black. Unfortunately, transparency is not retained in images resized for a gallery and it is not possible to pick the color for transparent regions.

The best thing to do would be to resize your images (as PNG images with transparency) in an imaging program (such as Adobe Photoshop) prior to using JuiceboxBuilder-Pro.
In JuiceboxBuilder-Pro's interface, deselect the 'Resize Images' checkbox (on the 'Images' tab) to prevent JuiceboxBuilder-Pro from further processing your images and your source images will be copied across to the gallery's 'images' folder (with transparency intact).

I hope this helps.
