You English is fine; I wish other members could post their question in such a clear language free from ugly spelling mistakes. However, your problem looks artificial. You put some unmatched data in controls in first place and later wants to match items. Why?
You should do the following: you need to separate your data layer from UI. When you want to find anything in data, an actual data element of some relationship, find it in data, not in the UI control.
As to your problems, you can do one of the following: 1) do not store images and file names separate, work with a list of structures containing both; 2) create a dictionary, such as
indexed by the file names (say, lo-case them before using as a key); that will give you a fast O(1) search of data by the file name (if you don't know "Big O" notation, read http://en.wikipedia.org/wiki/Big_O_notation
After you got a proper data model, think about data binding to your UI. In a simplest but most flexible case, it could be as simple as two method: population of UI from data and update data from UI, but chances are, you might need more complex UI behavior, but nevertheless, do it using the data model, not just UI or data in UI. On these grounds, also critically re-think you UI design. I don't know your detail, but if you change your approach, do some development but face with problems, ask your further questions. Most likely I would be able to help, other experts will probably help, too.
