c++ image fix for webserver

Okay, i have a custom webserver written in c++, it currently only serves html need it to do images to. For images i just need it to pick a random one from a directory and print it out dynamically, so i had this routine written by somone on here int random_image(vector<char> &s, const char *path) { vector<struct dirent> l; int r, i; struct dirent *d; DIR *dh; [login to view URL](); if ((dh = opendir(path)) == NULL) return -1; while((d = readdir(dh)) != NULL) { if (strlen(d->d_name) <= 4 || d->d_name[0] == '.' || strcasecmp(d->d_name+strlen(d->d_name)-4,".jpg")) continue; l.push_back(*d); } closedir(dh); if ([login to view URL]() == 0) return -1; /* No valid images present */ /* Generate a random number in our list */ r = (double)rand() *[login to view URL]() / RAND_MAX; for (i = 0; i < [login to view URL](); i++) if (i == r) { FILE *f; char buff[4096]; int c; snprintf(buff, 4096, "%s/%s", path, l[i].d_name); if ((f = fopen(buff, "r")) == NULL) return -1; while((c = fgetc(f)) != EOF) s.push_back(c); fclose(f); } return 0; } Okay so the image gets stored in the vector called data. My http headers are stored in strResponse which is of type std::string strResponse += "HTTP/1.1 200 OK\r\n"; strResponse += "Date: "; strResponse += szDate; strResponse += " GMT\r\n"; strResponse += "Server: Apache/2.0.48 (Unix) PHP/4.3.4\r\n"; strResponse += "Connection: close\r\n"; strResponse += "Content-Type: image/jpg\r\n"; strResponse += "Content-Length: "; strResponse += szPageLength; strResponse += "\r\n"; strResponse += "\r\n"; Need to have the headers and image all stored in strResponse. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
