How to convert FileName(char) to the variable name and display the variable name image

I want to use uigetfile to call my picture file instead of using cd. But there is a problem, that is, FileName belongs to char.

Is there a way to convert char to the variable name, and then display the image.

clc; clear
if exist('PathName','var')
    if PathName ~= 0
    else
        PathName = 'c:\';
    end
else
    PathName = 'c:\';
end

[FileName, PathName] = uigetfile( ...
    {'*.jpg;*.tif;*.png;*.gif','All Image Files';...
    '*.*','All Files' },'MultiSelect', 'on');
load(strcat(PathName,FileName));
varname = genvarname(PathName)
I = imread(varname);
imshow(I)
axis on;

[FileName, PathName] = uigetfile( ...
    {'*.jpg;*.tif;*.png;*.gif','All Image Files';...
    '*.*','All Files' },'MultiSelect', 'on');
if ~ischar(FileName) && ~iscell(FileName); return; end   %user cancel
FileName = cellstr(FileName);   %if user selected only 1 then it is char

fullname = fullfile(PathName, FileName);

I = imread(fullname);
[~, basename] = fileparts(fullname);

imshow(I)
axis on;
title(basename);

Thank you for your reply, but there is still something wrong with the code. Can you please tell me how to improve it?

MATLAB command window:

Error using imread>parse_inputs (line 504)

The file name or URL argument must be a character vector or string scalar.

Error in imread (line 342)

[source, fmt_s, extraArgs, was_cached_fmt_used] = parse_inputs(cached_fmt, varargin{:});

Error in Untitled (line 24)

I = imread(fullname);

try

fullname = string(fullfile(PathName, FileName));

[Walter Roberson]

[FileName, PathName] = uigetfile( ...
    {'*.jpg;*.tif;*.png;*.gif','All Image Files';...
    '*.*','All Files' },'MultiSelect', 'on');
if ~ischar(FileName) && ~iscell(FileName); return; end   %user cancel
FileNames = cellstr(FileName);   %if user selected only 1 then it is char
FileNames = fullfile(PathName, FileNames);

numfiles = length(FileNames);

for K = 1 : numfiles
    fullname = FileNames{K};
    I = imread(fullname);
    [~, basename] = fileparts(fullname);
    imshow(I)
    axis on;
    title(basename);
    pause(0.5)
end

Thank you both, I made it
