Many thanks for your comment as successful Bruce, but the problem i am facing is with the command MorphologicalGrap, documentation is an example that I wanted to repeat with another image and i'm having a result that is not convincing and the worst thing is that I cannot find the cause of this error, i hope that you or someone else in the community can help me, here is what I am doing. Greetings and thank you in advance.

Thank you for devoting your time to help me solve my problem, I did the steps that I mentioned but the problem is that the maze that I am working on has the same input and output are no different as the example of the documentation of the MorphologicalGraph fuction, you know if there is any way to be able to tell mathematica input and output are the same? because by not indicating you that would not give any solution. Greetings and thanks again.

Ps. ..I am trying to find a solution to the labe01.gif file

If you convert your mazes to a grid, you can use the code from the documentation to FindShortestPath.

You can check if there is a solution by using MorphologicalComponents e.g.

Colorize[MorphologicalComponents[Binarize[th]]]

It looks like the whole thing is connected, so not sure why there isn't a solution, though also not sure where the start and end are either.
