There are two major problems with your code. The first is that while (!feof(...))<\/code> will not work as you expect it to. That is because the EOF<\/code> flag is not set until after<\/em> you try to read beyond the end of the file for the first time. Instead do e.g. while (fgets(...) != NULL)<\/code>.<\/p>\n

The second problem, and the probable cause of your problem, is that fgets<\/code> reads not only the whole line, it also keeps the newline character in the resulting buffer. That means that if you have a line containing the file name hello.jpg<\/code> it will be stored in the buffer as \"hello.jpg\\n\"<\/code>. You need to check for and remove trailing whitespace from the buffer.<\/p>\n<\/p><\/div>\n
