Try this robust (but untested) code:
% Have user browse for a file, from a specified "starting folder."
% For convenience in browsing, set a starting folder from which to browse.
startingFolder = pwd;  % or 'C:\Program Files\MATLAB' or wherever...
if ~exist(startingFolder, 'dir')
  % If that folder doesn't exist, just start in the current folder.
  startingFolder = pwd;
end
% Get the name of the file that the user wants to use.
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullSourceFileName = fullfile(folder, baseFileName)
originalImage = imread(fullSourceFileName);
% Create destination filename
destinationFolder = 'D:\imagefolder';
if ~exist(destinationFolder, 'dir')
  mkdir(destinationFolder);
end
% Strip off extenstion from input file
[sourceFolder, baseFileNameNoExtenstion, ext] = fileparts(fullSourceFileName);
% Create jpeg filename.  Don't use jpeg format for image analysis!
outputBaseName = [baseFileNameNoExtenstion, '.JPG']
fullDestinationFileName = fullfile(destinationFolder, outputBaseName);
% Write the jpg file.  This will convert whatever format you started with to the hated jpg format.
imwrite(originalImage, fullDestinationFileName);
Do not be afraid. It's well commented - just study it a line at a time.
