Thanks for your help, I have tried your suggestions but they do not achieve what I was hoping for.
I have an existing AV which has text on each image. I would like to change the font type and colour and the text shadow settings to a different selection, I do not want to change the actual text.
I was looking for a way that after setting up one image to my liking, I could copy the above parameters and globally apply them to all the remaining images rather than having to individually adjust each image.
