However I am re-doing my site and want to have more control over how the images come up … namely once you click an image and the screen goes black with the image enlarged, I want to be able to replace the black with a different colour or even a background image.
Does anyone know how to do this with Slimbox, I am aware it would mean editing the CSS file.
Or, does anyone know of any other actions that could give me a similar effect for my gallery and give me more control?
Have a play with the styles; the colour, background image and opacity until you get something you are happy with.
If you want to do this in a more Freeway-like way you could add this style using the Edit > Styles dialog.
Regards,
Tim.
