I'm getting this for 'mathematics', for example. I can think of a couple ways of handling this.
1 - do another tumblr query to get more posts, and hopefully more photos
2 - use blank images
3 - repeat previous photos
4 - get photos from another source, e.g. google image search
I run into this issue a lot. It seems to happen more often when the search is plural.
Maybe there could be a process:
Try stemming the word before image search
Try synonyms of word
Google image search
Maybe add some random images to choose from for any pReSeNtRaTiOn (they might come up often and it might be fun for pReSeNtR connoisseurs to begin recognizing them).
if there are 1 or more images, just use those images multiple times.
