I'm concerned that image links might not be visible or work properly.
What makes you concerned about that? There are posts with more than 50 images and they are all perfectly visible and working properly, see
this thread as an example.
As suggested by other members above, just find the perfect height and width for your images and position them well within a single post. You can always use the "hr" tag to separate the sections for different entries and it will look good, for example:
Entry 1
[image]
Entry 2
[image]
