Sounds like a nice idea; but how will it work in practice?

Could it interfere with spider activity, losing you your image search results and maybe more?

no it wont interfere with spider, I am made a php script that detects whether user came from search engine or its direct user. All I need to add google image search robot in that script and rest of the job I already described ;)

...redirect them to a page where image belongs is not only useful for user but also for us in many ways such as, generating revenue from adsense or other networks, providing more useful contents to users...

This is a question with an interesting twist. As I interpret what you're asking, I assume you're wanting to redirect searchers who click the "See full-size image" link, not to the image file, but rather to the page from which Google extracted the image... ie to the "original context" url, which Google also returns.

In web search, Google doesn't like redirects from the page shown in the serps to a different page. In its Webmaster Guideline on redirects [google.com], Google says about redirects...

Sneaky JavaScript redirects

... it violates the webmaster guidelines to embed a link in JavaScript that redirects the user to a different page with the intent to show the user a different page than the search engine sees. When a redirect link is embedded in JavaScript, the search engine indexes the original page rather than following the link, whereas users are taken to the redirect target. Like cloaking, this practice is deceptive because it displays different content to users and to Googlebot, and can take a visitor somewhere other than where they intended to go.

Here, you'd be redirecting visitors from one url returned by Google (the image url) to another url returned by Google (the page url). Very intriguing question how this would survive a manual inspection, if Google even looked beyond the fact of the redirect.

Exactly right Robert. Any redirect to achieve this objective could annoy Google possibly getting all your images kicked out of the index with the possibility of some sort of sanction against the site as a whole.

My Opinion only, but those would be my fears.

Thanks Robert for updating me. I started this discussion to not violate any rules. I have still few things in my mind. In order to avoid losing such traffic we can create more possibilities. PHP has endless possibilities. For instance we are not redirecting users to any page and we will show exact image what Google sees but can't we add more relevant images at the bottom and also placing google ads at top will cover bandwidth cost. How about this?

PHP has endless possibilities....

So does Google. ;) I assume that if they don't have an auto-detect to spot redirection via whatever scripting language you use, they will eventually. Scripted redirects should be easy to spot. The question is, what will Google do about it?

There's all kinds of "cloaking" and redirection being used that Google doesn't object to. Browser sniffing, eg, could be regarded as a redirect that's OK. Google's main criterion has generally been whether the user sees, in essence, what Googlebot sees.

In this case, Google is doing something which some people encourage and other people (myself included) don't like... they're deep linking to your images.

The tradeoff is that they offer you lots of traffic... and they provide two links, the deep link to the image, and the link to the original context (which probably not many people use). You're wanting to provide a redirect to modify this latter situation.

Discussions on cloaking/redirect topics ultimately tend to become philosophical, and I've seen them go on for many years, more often than not with no resolution. The questions here are how would Google react to the redirect, and whether Google would have the discussion with you if they reacted negatively. My guess, is, that there would be no discussion and that they would react negatively, but I don't know.

I should add as a PS that you make some excellent points (eg, the idea of setting something up to display Adsense with the image)... but that Google would probably want to control how this is done, not leave it to individual users.
