If I've got this right, you want to use one image , say fluffycat.jpg and make several copies of that image and rename them according to the names of images in a directory.
Assuming using windows
Put the stuff below the #### into notepad and save it in the directory the images are in to whatever.bat (choose save as type all files)
Also put fluffycat.jpg in that directory
double click on whatever.bat and you should end up with a folder called renamedImages.
Ps I accept no responsibility of this script ;)
backup the images before trying
::Puts a list of all images in the directory this script runs into into a file.
dir /B *.jp* > images.txt
dir /B *.gif >> images.txt
dir /B *.psd >> images.txt
echo creating folder
::Reads each line of the file we just created
for /f "tokens=* delims= " %%a in (images.txt) do (
echo copying image
copy fluffycat.jpeg renamedImages\
echo renaming image to %%a
rename renamedImages\fluffycat.jpeg "%%a"
