Export_fig conversion help

I have 4 matlab scripts, each saving a figure at the end as a png file in a folder.

I have a different script which I want to use to export all 4 png files at once using export_fig.

Problem: how do I "load" the saved figures into the script so that I can convert them using export_fig?

code right now:

export_fig fig1.png
export_fig fig2.png
export_fig fig3.png
export_fig fig4.png


ERROR:
Error using export_fig
No figure found 

this export script is in the same folder as the 4 scripts which generated the figures and the saved figures themselves

If you saved your figures in a FIG-File, then

fig_handle = openfig(filename)

will open it.

Here a link to openfig documentation.

I have the figure saved as a .png file, sadly can't open it with openfig

Oh yes, then maybe try

 img = imread('fig1.png');

and then you can convert it with

 imwrite(img, 'fig1.jpg');

Or plot it

 image(img)

to use function export_fig
