I would have to see your website/layout to give you an idea...things are really more grey than black and white when it comes to clicks, etc. Hard to give definitive answers.
Image hosting is likely to be very low CTR, while a content rich site would likely be a higher CTR. I would say you may be lucky to get $1 a day with 200 unique visitors to an image hosting site, while a content rich site could expect to get at least $1 a day and maybe average of somewhere between $2 - $5 per day. The actual average will depend on numerous things such as ad-placement, the niche content and the type of visitors, whether organic from search results or coming through other referrals.
