Image Converter

Hi Gavik Team,
this is a question for graphic team. In sporter template I've noticed that you have used a background with high level of details but with low weight (about 260k). I've tried to modify the background with photoshop but when I try to save it the result is not the same as the original. This is my question.

How can I get an image with same high details and at the same time with a low weight using photoshop or another software?

Thanks in adv.

in photoshop if you choose save for web, you can play around with the settings for png files, and get a highres picture with small size... also, disable all hiden layers / gather all layers before saving will spare some size

Thanks a lot for your reply. I will try your suggestions.

let me know how it goes...
