Is it better to merge an image with the background or create a master slide - in consideration of final project size?

merge background vs. master slides

I worked for a company that decided to update its company logo. We had to edit all the eLearning courses because of the branding change. Because it was common practice to merged the previous company logo to the background image we discovered that keeping items like this separate was the way to go. We ended up having to edit all our background images instead of merely updating one logo image from our library. It was a lengthy process because we had to update hundreds of courses.

Yikes! That was a tough consequence for an ill-informed choice. Sorry that happened to you.

In my case, the company logo is not needed or included as a "seal" throughout, these are meaningful images used as various backgrounds, so my concern is simply to learn best practice to keep file size as low as possible without losing quality to the extent of obvious pixel grain/fuzz etc.

If you can use a SVG instead of a bitmap image, I would do that.

Which background? Project background, master slide background, slide background?

I certainly recommend using the master slides: you are always in a theme, and master slides are part of the theme. Why do you want to lose all the advantages of master slides, and the main master slide? If you merge an image with the background on a slide, you have to unlink the master slide it is based on. You can merge an image with the background on a master slide, that can be fine.

Sorry, was referring to merging the image to the individual slide background vs creating a master slide with the background image (unmerged on master). I tend to create master slides (old PPT design habit) even in Cp. I have created 33 master slide with unmerged images, but only about 12 are used repeatedly.

Wondered if i might be able to reduce overall project size by (thinking it's caused by images, since only one slide has audio less than 2min) if I eliminated the single-use master slides and merged the images used to the background of the actual slide and kept only the masters that were multiple-use.

If the master slide is used only once, I wouldn't create a master slide, unless it takes over some objects of the main master slide like navigation buttons, control buttons, logo. As I mentioned you can also merge images into the background of a master slide as well. I never checked out the impact on the file size, but my intuition tells me there shouldn't be a difference if you merge images in both cases. To decrease file size, make sure the images have exactly the needed size, do not resize them in Captivate. When possible, replace a bitmap image by a SVG which will often lead to much smaller size.
