Thank you for replying.
When I try your suggestion I get this error:
Could find no file with path 'res_%d.png' and index in the range 0-4
res_%d.png: No such file or directory
So the filenames start from res_05.png till res_180.png but there are some
files missing in between like res_13.png etc.
Would that be a problem?
Thank you again !
