Our site is based on a CGI script called Imagefolio which has been heavily modified. It displays thumbnail images dynamically from a flat-file text database. It also displays the IPTC fields from each thumbnail image. For example, if it displays an image with the filename of [url removed, login to view] it should display the IPTC fields from tn_track01cd002.jpg. However, for some reason, the script is looking for a file called [url removed, login to view] ... the "tn_" is missing.
So that is what we need fixing. I can point you to the part of the script that deals with the display of IPTC data and then you need to ensure that it prefixes each filename with "tn_".
Note: everything else, such as IPTC, is working. We only need this specific filename issue fixing. Also, this is a live and complicated site. You need to change as little as possible to get the problem fixed. I can send you copies of the script by email for you to look at before deciding whether you want the job.
