You need to check if the PNG bytes are 1:1 the same as the PNG bytes in the file you specified in the flexiinjector. If not, that's the problem.

One way to work around this is to take the PNG bytes in the HTTP request you see, store them 1:1 in a file on the disc, then specify that file in Flexiinjector.

This is not an issue with the upload scanner, it told you exactly what the problem is: "flexinjector configured but file content not found in upload request, rare case of javascript changes?"
