Finding A Cell Reference In An Array

I'm setting up an Excel (2000) sheet to record the results of a competition at my local photographic society. I'm trying to make it as simple as possible to fill out by the people using it, so have shaded the cells that require the user to put data in. I'll post a screenshot of the sheet, which is named "DPI", to make it easier:

(EDIT) screenshot removed - see attached file in post #3 below instead

I use one row for each member entering the competition. Each member can submit up to three photographs for judging. The names in B5:B30 are tied to the member number in A5:A30, and pulled in with VLOOKUP from a separate sheet containing all the club's members. The names in this example are, obviously, fakes. ;-)

The three blocks are to enter the image titles and associated scores. I have a range called "scores" which is defined as =DPI!$D$5:$D$30,DPI!$G$5:$G$30,DPI!$J$5:$J$30

The rank columns are simply calculated using the RANK function. E.g. the formula in E5 is =IF(ISBLANK(A5),"",RANK(D5,scores,0))

The cells at the top are calculated using the LARGE function upon the defined range "scores" (although they could equally use the SMALL function on the rank columsn instead).

The bit I'm stuck at is what I want it to say along the top. eg: "Leg 1 Winner: 30 is {insert image title} by {insert member name}"

Using the winner as an example, I want to take the winning score shown in D1, find it in the named array "scores", and return the image title to the left of it. Obviously I can't use VLOOKUP as the data is to the left of the lookup value as well as being in multiple columns. I wanted to use OFFSET to return the value of the column to the left, but to do that I need to pick up the reference of the cell containing "30" i.e. the winning score shown in cell D1.

How can I find this cell reference? Or is there a better way? I thought about the old MATCH/INDEX function, but INDEX doesn't seem to work very well with data in non-contiguous arrays as I'd have to specify which block to look in.

Once I can get the image title returned I hopefully sholdn't have any bother extending it to return the member name from a fixed column, but I can't figure out how to get the reference of the cells in the "scores" array that contain the winning scores shown in D1, D2 and D3.
