I am building a web site and the main objective of that website is to show pictures. My problem is is that i want to reduce the capacity of my pictures. Because they weight enough. Tell me tips that can be helpful for me. Thanks in advance.
Deferent extinctions uses deferent compression ways, so you should check another file format. 4 example .psd can weight 100 more times then the same file in .gif file.
You have to know that gif file format was created for web browsing and building site. So this format will be just corresponding for you.
If you're using Photoshop, you can preview different file types and compression levels, and choose the best compromise between size and quality.
Another solution is to use thumbnails, and warn people that the actual photos are big. However, you should scale them down to 72 dpi, and reduce the dimensions to less than 800x600px so they'll fit in a browser window without scrolling.
Hope this helps!
Why not make thumbnails so loading time will be faster? Increasing the compression when saving will definitely affect quality.
