slidemaker
slidemaker makes an html slideshow from pictures. It is written in shell (bash) script and is usable on OS X and most other Unix type operating systems.
Important: slidemaker searches for pairs of folders; one which contains your pictures and a second which contains small format pictures. Suppose you have pictures from Paris and London and you want a separate slideshow for each. Create a folder titled 'Pictures' (in Desktop for example, you can use a different name than 'Pictures' if you need/want to) and in this folder create subfolders, titled something like 'Paris', 'Parissmall', 'London' and 'Londonsmall'. The folder tree should then be
Pictures/Paris
Pictures/Parissmall
Pictures/London
Pictures/Londonsmall
The word 'small' may have capital letters, but it is essential that the first part of the name, e.g. 'Paris', be the same for that pair. Also, don't use names like 'Paris' and 'Parissands' in order to avoid confusing the lexigraphical order.
Finally, export your pictures (.jpg, .tiff, .png files etc) into the "nonsmall" folders. Export small versions of these pictures (100 px in width is preferable) into the "small" folders. The names of the contents of pairs of folder must be identical! For example,
Pictures/Paris/ contains
DSCF1314.jpg
DSCF1314.jpg
DSCF105.tiff
Pictures/Parissmall/ contains
DSCF1314.jpg
DSCF1314.jpg
DSCF105.tiff
Directions: Once you have created a directory tree and exported your pictures as described above, do the following steps.
cd Desktop/Pictures
sh slidemake
