Hi I need detail on using pictures in c code.My system has to upload,store and display picuters.Please help.
Unfortunately, there is no standard way to read and display image files in C; it would depend on the operating system, the windowing manager, and the graphics library you are using. There exist several portable windowing libraries such as Qt, wxWindows, and GTK+, which include the ability to display image files as part of their operations; if you pick one of these, you should be able to display the images fairly easily. Otherwise, you would need to let us know what system you were targetting this for.
Also, what sort of image files do you need to display? There are several formats in widespread use, including GIF, JPEG, PNG, BMP, SVG, and TIFF. Do you need only one type of image file, or do you need to support several different ones?
