Thank you for the quick response! Well, the desired output is a big image of all files in that folder. The imagemagick convert command joins given imagefiles together, either vertically (-append) or horizontally (+append). So what the script should do is select the files that belong together by the first part of the filename and then join them via the convert comand and save them with a prefix and the first part of the name, then select the next files that belong together...join and save them...and so on. At the end I would end up with a bunch of horizontally joined files, for example:
row_11.123456.png (File1 and File2)
row_12.843211.png (File3 and File4)
In a second step these files again will be combined vertically, but I think this can be achieved simply by running the convert -append command on them. Hope I could make it a bit more clear...

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
