Thanks for your interest in Aspose.Slides.
As I shared with you in my previous post that Aspose.Slides does not provide front end support as it is an API that manages the presentations programtically and generate desired presentation. This is in fact not a missing feature in our product as domain of Aspose.Slides is to programatically generate presentations.
However, Aspose.Slides does provide the support for generating the slide thumbnails or slide images in Jpeg, BMP or PNG format. You can generate the slide image can show that as image in Internet Explorer. Please visit this documentation link
for your kind reference to get to know how to generate slide thumbnails.
Please share, if I may help you further in this regard.
