I'm presenting an alternative for you if you don't find a slideshow program you like. Also, curious as what you did not like about the LR Slideshow Module as what you do sounds pretty straight forward. I do agree that it is very basic. If you are using the Adobe LR/PS package for photographers you also get access to a program called Spark. In your Cloud Adobe icon go to Social Media and then Spark. Launch Spark, there is no additional fee for its use. Click on the + sign at the top and a row of choices will come up. Pick the Web Pages. You can put any number of images and text into the web page you design. This page will be kept in the "cloud" and you can access it from anywhere for use. You can also download as a pdf, put into Facebook or an email if you want to. The software does not come with directions so to learn it you will need to simply poke around. I'm including a link here to show you a quick little page I put together. The options are endless. Storing it on the Adobe server is nice because then it does not matter how large your presentation gets, but of course you would need internet. Just a thought. https://spark.adobe.com/page/I9lPmgsfWs3Ob/. Also, if you use a Mac FotoMagico is for Macs and is a program with many more options than the Adobe LR software. You can ind this program on the web or at the Apple store.
