Its actually very useful. A limited number of parameters can be genuinely altered - a better photo can be taken, and vaccinations can be administered for example. Animal rehoming centres have to balance throughput with cost; reduced per pet costs mean that they are able to expand or support more complex cases. Whilst keeping a pet in a "space" and feeding it does cost, this cost can easily be significantly less than vaccinating, particularly as some vaccines require a few days hold post vaccine. Similarly if the vaccine will not alter a pets rehoming chance, then it is an unnecessary cost. Pictures may be more easily applied as a tighter feedback loop (of the 5, use the 3rd) however they may also indicate other issues that could be addressed (over / underweight, coat damage, etc.) and addressing those issues have costs to balance and predict.
