Subject: fixed pagination to work correctly on index page
X-Git-Url: https://git.nubati.net/cgi-bin/gitweb.cgi?p=photo-tags.git;a=commitdiff_plain;h=801ba916b5b5680e10c3b63978034058f7fed840

fixed pagination to work correctly on index page

main problem was asynchronus call to handle json data where some variables were set. those were not available in time at other places. fixed by moving those function calls inside the json loop
