file i/o operations with images

[natashadams]

hello all:
I'm trying to insert images into files but not quite sure how to do that. the images can be of jpg, bmp ,png formats. I'm not aware of how to open the file, insert the image into it and view the contents of the file when necessary.Could anyone please share some information on this? Thanks in advance and appreciate the help

Regards,
Natasha

The GD graphics library is an excellent API for working with images :

At the lowest level, you would use
- fopen
- fclose
- fread
- fwrite
to manipulate the file. Don't forget to use "rb" and "wb" when opening the file.

As for file formats, BMP is definitely the easiest to manipulate in code terms. If you're really into doing the file yourself, you need to check out the file formats. This site has descriptions of many formats.

But a library is definitely worth looking into if you can.
